I'm picking up an old 90s bike and want to run it 1x. This is the cheapest option for cranks, right? Just remove the big and small ring and use the cranks that came with the bike so I don't have to fool with a new bottom bracket and worry about getting another crank with the right chain line, right?

It is, that is not a problem. Although I would recommend a BB with a smaller spindle. If you don’t want to buy one and have trouble with chain dropping, just use an old front deraileur as chain guard.
Certainly looks like that is the case…I’ve done the same myself with a 2x FSA Gossamer crank and a 40T chainwheel…
As long as the chain line is good I’d just keep using it.
I am doing this with FC-6206 triple and a stock width and offset bb. Works great, chainline is perfect for friction shifting 1×10.
Yes. Note you probably need new chainring bolts, the 1x bolts are shorter.
I converted a couple different old mountain bikes over the years from a triple to a 1X and this is a completely normal thing to do. If the chain line looks okay and it shifts through all the gears, you should be fine. I highly suggest doing the wide-range 11-48T cassette and the MicroShift Advent X 1×10 groupset. Cheap and good quality. Close to the same range as a modern 11- or 12-speed for a fraction of the cost. Rode an old MTB with this setup for years with no issues!
Good luck with your build!
Yes, but check the specs on your crankset. Some cheap cranksets are riveted or used a weird bolt circle diameter
