Hey, thanks for the reply. Great advice! I looked into the crank length topic, and it definitely makes sense now. I’ll try to find a setup with a shorter length (155-165mm) and sell my power meter.
Unfortunately, getting a setup with a spider power meter or power meter pedals will be more expensive... 
I guess the cheapest option would be to go with 165mm crank arms. Will I regret not going shorter, like 155mm?
I am probably missing something, but i dont understand why pedal based power meter isn't the go to for most people. You can swap between bikes, you can travel with it, you can put in the home trainer and outside to get consistent readings, you can upgrade your bike and keep the same pedals. I've had the vector 2 from garmin since the great war of 1914. It's done dozens of thousands of kms, and well, it just works. The only thing i dislike is it uses coin batteries, but it's so old, rechargeable PM didnt exist then.
Bike tech does evolve. Quite fast, in fact. Discs, wider rims, shorter cranks, hydro brakes, and so on. Throughout all of this, the one constant has been my vector 2. I've probably used it on 10 bikes. And it wasn't that expensive to begin with (i have the single sided one, because unless you had an accident, you're probably balanced enough, and having one dummy side means there's one electronic thing that can break of malfunction instead of 2).
A friend bought the dual sided speed play power meter, for a literal fortune, and it never seems to work properly.
