@WombatWarrior17 Just my 2 cents, I learned (and forgotten) full ttll, and tbh the ergonomics for most of the algs are not much better than zbll algs (and 2gll has really great oh ergonomics).
I am sub 17 oh and sub 12 2h with coll and 20 zblls. I think getting eoline sub 3 and f2l block...
The way I think of eo is in 2 simple rules, Front color on front and top color on top. If a f/b color is on u/d, then it is wrong, and similarly for u/d on f/b being incorrect.
If your willing to drill, sune/antisune colls are pretty alright (ive always used them cause my pll sucks as a zzer), although if you can sub 2-3 ll with sune and pll than its not really worth it.
This is the older method of csp tracing, which is similar to bld tracing. The newer method is by Cale Schoon and I find it easier to follow.
(all the cubeshape algs are in the description (not mine)).
Easies thing you can do is learn all the eo algs (there are only 5). Than next is to learn some more basic eps, like adjacent swap on top/bottom and opposite/o perm. For cubeshape and alg drilling, squanmate is a good tool https://github.com/sp3ctum/squanmate

For your eoline, your solutions are pretty decent, however you should keep track of the DF DB edges and track first pair so you don't need to pause to look for them. Your F2L is pretty efficient, but riddled with lengthy pauses. Find a good balance and improve between pair solving time and...
I do my eolines usually a y or x from the face I do eo on to make it more ergonomic (if I can plan an eoline that doesn't use the R face, I'll put that as B and do eo a y' from front) This is kinda like how asmallkitten does his eoline. (I'm sub-18 with zz OH)
