The "GTO" value bluff ratio, 1 to 2 value bluff ratio on flop, 1 to 1 on turn and 2 to 1 on river.
But it's not "GTO", except in artificial/toy games where one player has a polarized range (value and bluffs) and the other solely has mid-strength bluffcatchers. Real poker is not like that. On most boards, both players have a mixture of nuts, mid-strength, draws, and air.
That said, if you get to the river and want to bet POT, then I think the range you bet with should have about 67% equity against a calling range (i.e. it's roughly 2:1 in favour of value). Some hands will win much more often (the nuts), some will win slightly more than half the time (thin value), and some will almost never win when called (bluffs).
On the earlier streets you'll bet with more unpaired hands, but they should often have a chance ("outs") to turn into value hand later on.
P.S. To answer one of the other questions in your initial post, if you choose to bet small, your betting range should contain fewer bluffs, because you're more likely to get called when you bet small. e.g. If you bet half pot on the river, 75% of your range should be beating the calling range, and you can only "get away with" bluffing a quarter of the time against an optimal opponent.
