Good news — you don't need to memorize F2L the way you memorize PLL. With 2-look OLL/PLL already in place, intuitive F2L is the natural next step in CFOP, and it's mostly understanding, not memorizing.
Start with just three ideas:
1. If a corner and its edge are already paired together, just insert them into the right slot.
2. If they're separated in the top layer, bring them together first — usually by moving the corner up, then the edge, or vice versa — and then insert.
3. If one piece is in the wrong slot, get it out to the top layer first instead of forcing it.
That's most of F2L. The rest is the same few patterns showing up in different slots and orientations.
A practice routine that helped me: do untimed solves and stop after the cross. Solve one pair slowly, look at what the pieces are doing, and try to do it in as few moves as you can. If a pair feels awkward, set it up again and try a different way. Don't time these — just do cross + F2L, then scramble again. Once the basic pairings feel automatic, your timed solves will drop a lot without learning a single new alg.
This CFOP guide lays out that order — cross, intuitive F2L, then 2-look and full OLL/PLL — if you want a clear roadmap:

Stick with the intuitive cases for a while before worrying about advanced F2L algs. You'll start recognizing them in real solves much faster than you'd expect.
