IMHO the recruiting side is over-indexing on very specific technologies rather than personal skills/capabilities (oh, you are a C# expert, great, mind learning Java?). To fight that you could make your resume more buzzword compliant - do a small project in AWS, write a blog post or create a YouTube or TikToc about the differences/similarities, and do a couple of certifications.
These help me stay sharp and up-to-date: Audible (app on iOS, books on tape) Podcasts (app on iOS) Pluralsight (video training on iOS and Surface and desktop) Meetup.com (I run a user group, bostonazure.org, and attend many)
Coding: GitHub (code, mostly free, but use a few private repos at $7/m) Azure cloud (various storage, VMs, Websites, databases, ...) Sublime Text (programmer-friendly customizable editor) PyCharm (Python development environment)
Fitness: Fitbit (paid for device, app came free)
