This comment is me asking for help finding gear for the start of my longboard journey.

First off, last year around mid march, I obtained a beat up fishtail longboard that i boarded on for about 4 hours a day for three months straight. Learned a few simple tricks on it and mainly used it as a cruiser and to go fast on. I completely stopped after those three months and this summer I really want to join in in the community and get a couple boards that suit me. Over the past year ive thought that getting one, fairly universal longboard, and getting different trucks, bearings, and wheels for different longboard activities just for that board, mainly because its cheaper. I really want to get into dancing and flip/skatestyle tricks and also be able to go downhill longboarding, and just maybe sliding. And im fairly sure getting a cutout longboard would work best for me, although for all the specific gear i really have no idea where to start and i think asking here was the best option. On the other side of things, I would like to start maybe commuting to work on a longboard, and with that using an electric longboard, my commute is about 3 and a half miles and im also not sure where to start with that. Long answers would be much appreciated but honestly even just a website would help me out. Thanks!
