So according to this video by Spacedock boarding an enemy ship or station isn't as easy as it looks in Star Wars. Meaning hard docking your main ship to the enemy is usually used as a last resort. The other option is to either have a pre-made or retrofitted transfer ship/shuttle/pod that is designed for boarding other spacecraft. In the event that their target's weapon systems are still active either the transfer vessel or main ship will increase their odds by sending out decoys and missiles to cover the boarding party. The Boarding party will either access the ship by either a) using some fancy flying to access a remote docking port b) soft docking with the ship, meaning cutting your way through the hull, provided you have knowledge of which part of the hull to cut through to avoid rapid decompression, hitting a fuel line, or something just as bad, or c) if you are very lucky go through the hanger bay if the door is left open and undefended.

There is also a good chance that the boarding party will be wearing spacesuits in the event that the enemy tries to cut off life support in whatever deck they are or tries to eject them into space. The spacesuits will be armored as well in the event they will get into a fight with any defenders or defenses that are on the ship or station. That said the video is a little vague on what kinds of weapons would be used for a fight onboard a spaceship/space station.

It mentioned the use of good old carbines and submachine guns, but if watching For All Mankind has taught me anything is that it's a bad idea to use kinetic weapons inside a close-spaced environment made out of metal. The last thing you want to worry about is the ship blowing up because you damaged some systems during a firefight or being hit by ricocheting bullets.

So what kind of weapons are the best for a fight inside a spaceship or space station? Laser rifles/rayguns? Handheld particle beams? Or are kinetics still your best bet? Note: Plasma weapons are out of the question due to being impractical, unless you are thinking of using them to cut your way through doors and wall.
