Advice for New player to Baldurs gate and D&D

Hello as stated in the title I am completely new to Baldurs gate and I just recently downloaded the Baldurs gate 1 and 2 enhanced editions from the Xbox game pass, I just did the tutorial yesterday and my head still hurting abit from all the information and tips they had to give, I created my character to be a fighter proficient with two handed weapons not sure if this was OK. Does anyone got any tips because the informations from the tutorial was really overwhelming for me, what should I expect in the game and what are best ways to improve when playing.

Thank you.
