When I built up my rando bike five years ago, I was not sure what to use for a front shifter. As a temporary measure, I used a vintage friction downtube shifter, but now five years later that temporary measure is starting to look very permanent. They work with all bottom pull derailleurs.

Regarding long cage rear derailleurs, there are tons of used ones. I like the look of the 1990s vintage XT rear derailleurs, have them on several bikes plus a few spares on the shelf. Pick something that looks nice, check to see what the cable pull ratio is on it and try it if the math looks good.

Jtek adapters can be used to change cable pull ratios if you are trying to mix and match.
