I learned basic accounting at a community college-- Financial Accounting (3 hr course) & Managerial Accounting (3 hr course). I later took Intermediate Accounting 1 which was also super insightful.
But those first two... Wow. They really opened up the "black box" of internal financial operations within a business, to me. Prior to those first two courses, I had no idea what happens when I pay a cashier a dollar, and how that dollar flows through a company to pay their vendors & employees (as well as taxes).
Intermediate Accounting 1 & 2 (dropped out of 2) taught me more about how accounting statements relate to the stock market & financiers.

Accounting knowledge + Digital Marketing experience has been invaluable to me as a Software Engineering consultant (in the digital marketing & small + medium sized business space)-- I understand the language of business and can predict what a customer needs much better than I could before.

Finance on the other hand is a bunch of mathematical formulas that are usually dumbed down. With OP being technical they should be able to learn the finance stuff on their own.
I'd venture to say with a solid understand of financial accounting they can probably learn financial statement analysis on their own too. I really like this book: https://www.amazon.com/Financial-Statement-Analysis-Practiti...
I had a skillset of:
A. Promoting products at events as a Brand Ambassador
B. html, css, and basic frontend javascript self-taught skills (from ebooks, youtube, udemy).
With skills A & B, I successfully justified that I should be hired into an entry level digital marketing role, where I used Marketo to email-spam B2B and set up web landing pages.
Once I had that initial job using Marketo software at a B2B software company, it was much easier to lang other digital marketing roles.
The world of business is large. I'd probably read up on the particular domain your focusing on (real estate? sales? telephony? etc). Find subject matter experts at your company and take them to coffee and ask what they read or recommend.
When I took it, it was still $250. The course was free and you paid to take a cert test at a testing center. The following year they made the whole thing online and free.
Accounting for one is recording what has already happened in a business - its merely reporting, nothing more. Its a reporting function of business.
There is far too much focus I feel on accounting and finance in MBA courses. Its not business.
Business is finding people and having them pay for value - a product or service. If you have an accounting department or knowledge of accounting/finance, you don't have a business, you have reporting. That's all you have.
Business is far more about sales, marketing, pricing, psychology. Then there is the delivery of that value - the actual product or service.
Accounting/finance in a discussion of "learn business" should come way down the list IMO - its nothing more than reporting.
Put another way, I don't care how great you are at product - if you don't understand what costs and margins are required to actually turn a profit you'll still fail anyway.
Business is about numbers, yes - at all sizes of companies.
But what actually drives those numbers?
Its 1) value and 2) sales/and marketing. Its not the accounting department. That's my point.
Understanding costs and margins is crucial, yes. But its very much secondary to having a valuable product that people want and that you can market/sell effectively - that's business, not accounting/finance.
A developer asking questions about the value a product creates and the problems it solves or doesn't solve will do far better than learning accounting/finance as far as "learning business" goes or getting an MBA!
I'm not a Musk fanboy, but he has created multiple valuable companies (spolier alert, he didn't do that by focusing on an MBA but rather on creating valuable products) - here is what he has to say about MBAs in large companies:
"Spend less time on finance and power points and more time on making your product as amazing as possible". Bingo. That's business.
Its defined by people buying a product or service they find of value - that is core to business. If you don't have that you don't have a business (no matter how many accountants or MBAs you have).
Any skill can be taught.
A business without knowing accounting/finance, exist can. (An accountant, hire, one can).
For accounting/finance to be useful at all, a business exist, must first.
Without doing business and creating value, there is no accounting, or finance. Often Accounting and Finance exist to keep risk manageable and if you let it too long, avoid it entirely.
Creating Value is almost certainly working through some amount of risk.
In a business, Accounting and Finance on it's own may not always create value, unless it's an accounting/finance business.
Conversely, creating value without accounting and finance will make it harder to retain the value created.
Accounting and finance functions are mostly about retaining what is working and making it more efficient.
Innovation Accounting, is another thing that is not always measured on the P&L.
Next I would say, reading up on basic marketing/consumer psychology will help develop/acquire product and sell it.
Since you mentioned being CTO, I am assume you have development/programming background. This series [1] is good read targetted to developers who want learn a bit of accounting and finance.
