Welcome!
My biggest advice would be to completely forget about look ahead for now : you won't need it until your F2L is efficient and you're comfortable in your solutions (as in you can solve most cases in 8 moves or less, and you can execute your solutions blindfolded)
My second advice would...

You didn't solve the cube so it's a DNF: this solve and your best one won't count in the ao5.
Let's say you average 25s and you get the following times: 23, 32, 19, 28, 21
If you DNF the 32, nothing changes:
23, (DNF(32)), (19), 28, 21 = 24 ao5
If you DNF the 21, your worst time (32) will...

You can enter the scramble in csTimer with "Input > Extern" or "alt+i"
In the tools select "Solvers", and it'll give you a cross solution for every color.
For your specific scramble (F2 U2 D2 B' L2 F' B' U2 B' L2 B2 U R' F R' B2 R' B L' R' F), it gives you for white:
z2 F2 R D F R' B L
It...

You can also drill the algs that give you trouble, but don't focus on how fast you execute them, focus on using the proper fingertricks and not locking up.

You should solve pairs in the back
And if you already do that, try to take advantage a maximum of empty slots, especially if they're in the back: you'll get potentially interesting pieces out of them and on the U layer

Does any one know an Rb perm with headlights on left that doesn't start with a regrip?
I use R2' F R U R U' R' F' R U2' R' U2 R but I'd like a regripless one from start to finish

- You double flick E2s with your left hand like you would double flick U2'. You squish a bit the top and bottom layers with your right hand.
- You double flick the U2 with your right hand, as usual

Yes, it happens a lot in the beginning
What I did (and still do sometimes) is that I repeat the cross color in my head again and again, to stay focused on it.
It helps to find corners and to filter out any edge with the LL color

There's already a lot of videos on YouTube about that
If there are things they talk about that you don't do yet, start implementing them
If you already know/do everything they talk about, then just keep doing solves.
If you're not sure, film your solves!

E perms can be done from 2 angles, not 4.
If you do it from here or here, you'll get a solved cube.
But if you do it from here or here, you'll get an H perm

Tbh I'd just rotate, but I can think of 3 solutions
- d R U' R' : it's technically the same as y' U R U' R', but maybe you'll like it better
- F' L F L' : it uses F moves but it's more fingertrick friendly than U F U' F' (F' with left thumb, F with left index). Also "I'm bad at F moves" doesn't...

Don't start the timer :p
We're timing solves to mesure our progress, there's no point in timing them
- if you're learning something new: some people give up learning F2L or being CN because their times go up and they get demotivated
- if you're trying to break bad habits: time pressure will...

It took a bit of time but I was greatly helped by the quality of the video (even in 0.25 speed everything was clear). And I used Cube Explorer to find the scrambles.
Reconstructing your solves definitely took the longest time, so if you give me the scramble / reconstruction I can critique other...
