Making EM Guns Viable in Space Combat (3e)

[Witchking]

The usual answer in scifi fiction (at least that I have read) is:

FTL travel (whatever flavor) requires drives of a size that you get 'Battleships' or something similarly honking huge.

Fighters are possible, do damage outside their weight class, are not very survivable...and are carried in FTL buy a combination of Battleships, Carriers, etc.
