If we were meeting for the first time, this is where I'd begin.
You told me you're not sure yet what you'd like to change, you haven't done any strength training yet, and you get some occasional discomfort.
Not being sure yet is a perfectly good place to start. The first few weeks are about building a routine you can keep, and what you want usually gets clearer once you're moving.
You mentioned some occasional discomfort, so Move Without Pain is worth having alongside. It'll help you choose versions of each movement that feel good.

Does this feel like you?
Most people start in one of three places
Pick the one that sounds like you. You can always switch.
Or something more specific
Whichever you choose, here's how I'll coach it.
My job is to make myself unnecessary.
I explain the why behind every set, so one day you can write your own program. Technique comes before load. Progress gets written down, so it's a number, not a feeling.
Twice a week for a year beats four times a week for a month. And I'll never sell you fear, or a supplement.

So here's what I find myself explaining most. Read what's useful; skip the rest.
Some of it is just arithmetic.
So here are a few calculators. Each shows its working, and says what it can't know about you.
All of them
And when you'd rather not do it alone
Sometimes it helps to have someone in the room. We'd start with a short conversation: what you want, and whether I'm the right person to help.
