So how do I show them, on a resume, I'm competent if I don't have any jobs (of any time-length) to show them? If I have an assessment test that would be great, as I'd like to know how good I am with what I've done in the past like Microsoft Software for example. How about a cognitive test, I know I could ace that one, I think
As mentioned above, I would consider taking a few free short courses in the software you used to use. This way you can get familiar with updates to the software, and boost your confidence regarding those skills.
Sharpening your tools, and organizing them, will help you understand what jobs or gigs might be best suited for you currently. It might also while where you want to shore up your knowledge.
It'll have many benefits. Boost in confidence. Gives you something productive to do and work towards. Expand your options. Etc.
Give yourself the gift of knowing what you know, and what you don't. When you know, you can do something with and about it.
I just zero'd in on two jobs I really enjoyed. Both were in factories, but I liked that better than the desk jobs I had. These were pretty exceptional jobs for me as they were very "light-weight".

I loved that last one, totally light-weight, and I was right around 60 years old on both those jobs.
I'll do some searching and see if there is anything out there like that near me. Once I get busy in a job, I will take a class, unless the job is permanent and full-time. What I'd give to have a road-worthy comfy RV but I get turned down for personal loans and a vehicle loan because although I have very, good credit, my income is not enough for them. So all I can do is save. Every time I get a few hundred saved, something crashes on my vehicle, lol, damned if I do and damned if I don't
