I’m new to modifying bikes and i dont particularly change the parts of it because i’m a bit slow. i was wondering if a square crankset would fit this bb or do i choose the round one? i know for some of you this might be the dumbest question someone has asked in this group but im really lost…

square taper cranks require square taper bottom brackets, idk much about that type of BB except it needs direct drive cranks.
That crankset will need a normal square taper BB. The ultegra bb is for hollowtech cranksets that have a shaft that is directly attached to the crank arms and then you stick it through the bb
No dumb questions if they’re asked genuinely 👍 cranks and bb compatibility can be a little confusing. The cranks you posted are a square taper fitting which goes onto the bb that look like a 1 piece unit with a spindle and square ish looking ends. The bb you posted is for what is sometimes reffered to as direct drive. This is when the crank spindle is attached to either of the cranks. Often they are 24mm spindles but can be a gxp style spindle which is slightly different.
A square one, if this is something you get into long term, don’t buy shit on Amazon, when you have a better grasp of what you’re looking for, buy from independent online stores. I see people get burned in counterfeit, no name, or just plain fake Amazon listings all the time.
