I always recommend leaning hard into the good things that you like to actually do. If there's a technique that you like to practice, do it. If there's a technique that you don't like to practice, maybe fuck it. I go through phases where I gain or lose interest in different things such as learning music, drilling technique, or writing music. I never fight with myself about it, because once you start that internal conversation then guitar will probably lose to video games or watching youtube or whatever.
For learning theory, I'm kind of unusual in that I don't think it makes sense to prioritize it early on vs learning music and developing technique. It's good to know, but it's better to actually be able to play. The lessons here are super well-made, so just work through them at your own pace as your curiosity leads you.
For picking practice, I only improve when I slow way down to the point where I am in total relaxed control. No autopilot, no rushing, no mistakes, no trying to race a too-fast metronome, none of that. Don't get tense, don't get fatigued.
For overall practice tips, start by massaging the front and back of your forearms and let them relax. This is where your "finger muscles" actually exist, not in your fingers. Quickness, accuracy, and economy of motion are all lost when you get tense here. Take breaks as much as needed.
