The FD pull ratios are different. But back in the 7 speed era, Shimano typically used a friction shifter on the left. Only the right shifter had indexing. Like these Deore shifters:
These should work fine for the OP
Not necessarily.
Shimano ran 3x7 speed triggers. I currently have a set of 3x7 LX-563 and mid 90’s STX, currently in use on one bike, that I’ve run with various cranks.
But I do agree that friction for the FD, especially with a 2x, is probably the best route.
