11-36 is what I also run abet with a tight chain and no clutch on the GRX derailleur.
I found a tighter chain work wonder when riding on the smaller sprockets.
I have 1x9 in the GF bike and I left it slightly shorter than usual, but I tend to let chains as long as possible.

The old way is to do that to ensure it’s long enough to cross chain, nowadays this need to be avoided especially on the smallest sprocket where the derailleur may not have enough tension to stop the chain from skipping on the 11/10t cog.
