Copycat... Jkjkjk lol
For 2x2: Make sure you plan all or almost of of your face/layer in inspection. And turn faster for it too, a face/layer should only take 5-7 moves, and should be planned, so there's no reason to 'lookahead' during your layer. I'd also say the same for your cross as well, it looks like you pause near the end of your cross to look for a pair, then finish the cross.
3x3: honestly, you said "besides turning slower and looking ahead" but I feel that that's really the best thing at this point. Try to be looking at the other pieces while you are solving one pair, and know whether you are going to rotate or not. Like you say you are doing slow solves without a timer, but in the words of cyoubx, it's not slow down and find the pieces. An example of this is in the 2nd solve, where you solved a pair, paused, and did an R U' R' insertion for the pair that was right there. If you didn't have a V perm and your F2L was a little smoother, that solve would have been sub 18. Try to fluidly transition from one piece to another, and make sure you are paying extreme attention. I find that I can't lookahead well at night because I can't focus enough. Also, sometimes you may be able to turn at near your same TPS while looking ahead, so try doing that instead of slowing down. It may not always work, but give it a go. Sometimes I can turn at near max TPS and my brain is just firing like crazy and the lookahead is automatic. That doesn't mean I don't have to focus, however. One more thing you need to work on is your cross to F2L transition, and having a cross that you can do nearly automatically really helps. And also cutting down unnecessary rotations will really help, try practicing RUL scrambles and solves to help you get familiar with solving cases without rotations. I think I did an Ao50 with just RUL scrambles where a so,fed the rest of the cross and then just did F2L, and that really helped me avoid rotations. I have a more in depth video on my channel about lookahead if you want to take a look at it by the way.
I hope this helped, and happy solving! I also hope I didn't come across as harsh or anything, I'm just trying to help
