A lot of boss combats begin with a forced cutscene, so you get no surprise round. Along with lots of enemy types in act 2 and 3 that see through invisibility and cannot be surprised.
Split the team into 1-3. Let the 3 scout the area / loot / talk first. If they see any enemies, pull out your bow and start blasing and let the trio retreat.
The only cutscenes that are forced are from the main boss in main story. Any other minibosses can have their cutscenes skipped by blasting them in the face before they even start talking.
Joking aside, the build is still viable even in boss fight. If you want to be more useful, use 3 Warlock instead of 3 Fighter so that you can Hex them as a bonus action. Your DPS will drop for sure, but you going first with Gloomstalker will always knock down 1 foe, making the fight less hard.
