Coaching lessons are enough ?

I think filming yourself would be a nice option. One of those rigs that stick to the glass and record the whole match then analyze your footage and maybe even cut small clips and show your coach.

Not Padel, but when I played tennis and went through similar, I asked a couple of people who I played with regularly what they thought were my weaknesses/how they planned to beat me. Best free advice I ever got.

This is actually a good thing and your thinking is correct. For most of us, having a coach sitting on the sidelines when we compete is not really viable, so you have to improve on your ability to read plays as well as to be critical of your own decision making. You can request your coaching sessions to not focus exclusively on technique. Ask your current coach or look for another that's more tactics oriented.

Join group trainings or classes with player of your level or slightly above. Or ask your coach to organise these type of training to focus on game situations.

Some coaches offer to watch your matches like in professional tournaments, and give you tactical advice during your match. The fee is the same as taking an hour of private coaching with them, they just use this time to watch you play live and give you tips during the "changeovers". You can take advantage of that.
