The first way it's used is to describe buying stocks that are cheap relative to their current financial characteristics (price to book, price to earnings, price to FCF, etc). This approach is usually contrasted with "growth", which would refer to investing in companies with a compelling thesis and bright future ahead of them.
A second way the term "value investing" is used is to describe the approach of Buffett/Munger where the investor compares the current price to the present value of the future cash flows and seeks a margin of safety above that.
You can do passive investing in the first approach. Just go buy ETFs that weight towards value metrics, like Vanguards $VTV value ETF. You can't really do passive investing in the second approach, aside from investing money in the funds of people who do that for you.
An S&P500 index does stock selection too, it's just picking large-cap stocks instead of value stocks.
That's not completely true. The indices can involve plenty of human judgement, the S&P500 does, for example.
Yes, that's correct. They are orthogonal concepts.
Stock prices go up and down, but usually your goal is to buy stocks low and sell them high.
Growth investing looks to trending sectors and companies and lets say 'bets' on a certain future playing out and thus being good for certain companies.
Value investing is an investment strategy where you deep dive on the financial fundamentals of a company and determine your own measure of worth, or what is sometimes called a fundamental value. In essence your own financial calculations give you a fundamental value that you think the stock is "actually" worth.
Having done this for a number of companies you then keep track of the market, and when, and only when, the stock price drops below your own fundamental value price then you buy.
Munger and Buffet would pair this approach to also planning to hold the stock for the long term and see themselves as owning part of the business over many years.
Often a stock might drop when the growth story turns against it (eg. AI is more exciting than crypto stories now), and this is likley when Value investors would get into a stock as it was now below their fundamental valuation and hence predicted on their models to go back up over time.
Mutual fund managers can often be classified as having a value or growth or index approach (and others). And for most normal investors it's usually good advise to take advantage of diversification and back a few different approaches in building a long term focussed portfolio.
I've seen Growth and Technical investing be contrasted to Value. Growth being looking for companies which have not actualized revenue goals but appear to be able to do rapidly(they're growing, look for the ones that grow fastest), Technical is looking at trends and patterns (they're trending, catch the trend and get off before others do).
In my lay understanding Value investing looks for margins of safety through companies which are worth more on the books than they're shares are selling for, or where their cashflows make them look attractive relative to bonds of their equivalent grade. An example might be if AAPL took a nose dive and was selling for less than $167B (which is their cash on hand) that'd be an excellent Value play.
Or assume their equivalent bond rate was Single-B (Currently 9.5%) and their Price to earnings rate was less than 10.5 --> Buying AAPL would be similar to buying a Grade B bond for less than the current market rate.
Value by contrast is looking at current earnings.
Both are predictions of the future value, one just weights the current earnings high. While you often have a bias to one, generally you should consider both. Don't buy current income if growth says the company will collapse. Don't buy growth if the company won't grow to support the value in the future.
Value stocks are by definition boring and unknown. Think iron ore mines, regional banks, house builders, carpet makers, and other yawn-fest-profit-machines.
Whether appropriate or not, the term “value investing” is widely used. Typically, it connotes the purchase of stocks having attributes such as a low ratio of price to book value, a low price-earnings ratio, or a high dividend yield. Unfortunately, such characteristics, even if they appear in combination, are far from determinative as to whether an investor is indeed buying something for what it is worth and is therefore truly operating on the principle of obtaining value in his investments. Correspondingly, opposite characteristics—a high ratio of price to book value, a high price-earnings ratio, and a low dividend yield—are in no way inconsistent with a “value” purchase."

This is passive investing, not value investing.
Value investing is very much active investing, otherwise how would you select the undervalued assets?
Value investing is about finding undervalued companies and buying them while avoiding the properly valued or over valued companies. It has nothing to do with ETF's or index funds.
