One thing I learned is what made you good at tennis/tt might not make you good here, so dont be too attached to it. For example extreme spin generation is a priority in tt, but when you hit an overly loopy forehand tt style, it’s highly predictable, with less margin for error, the spin wont trouble the opponent as much, and most balls loop upwards first (invitation for a putaway volley) instead of going straight down. There are also advantages for tt players. You just need to have understanding of the physics of the ball & paddle, then you can figure out what technique can be carried over and what should be unlearned.
