Welcome to the forum.
I don’t really do exercises on guitar much any more but a couple of things I still do are:
Playing on one string forces my fret hand to extend.
Playing across a string - so for example using the A and G helps me get the right single string.
For both I just pick a key and play within the key.
If you want some free lessons go to Justin Guitar. https://www.justinguitar.com/
I know he has some stretch exercises that will help on that front & I am sure he has some speed exercises as well.
If you are willing to pay for a more structured plan, I would go to Truefire and look through their speed picking, sweep picking and guitar gym courses https://truefire.com/online-guitar-lessons/
