how are you supposed to know which side mission is which when only looking at the map?

so i wanna do the side quest for the katana thats good with sandevistan (i think the scalpel) and the other one where you get jackie's motorcycle but all of the side missions (the hollow yellow circles with an exclamation point in the middle,whereas a main mission is a full circle with an exclamation point) are are titled "side mission" or something like that in the map,so how are you supposed to know which is which without using a guide? or how are you suposed to know which soudns interesting or not without actually driving/fast traveling there yourself and reading the entry?

im refrencing this to the assains creed rpg games for example where every sidequest listed on the map have a title so you can pick and choose which ones you like


so are you just supposed to go in blind and guess?
