So with larger tires, to get the same comfort level you simply lower the pressure. However if you lower the pressure too much, particularly on a narrow rim, the tire starts to feel weird. Mushy, floppy, and less precise.

I haven't done enough experimentation to be an expert, but I distinctly remember replacing my 35C panaracer with a 32 on the front wheel and being much happier with the balance of comfort and handling. I blamed the wheel width, but maybe I should have blamed the T-serve casing.
Not sure what TPI the tserv has, but my tires are 120tpi Clement MSO in 40mm. Pretty supple casing for an intended purpose gravel tire.
Perhaps a wider more supple tire will be more comfortable. Pretty much every drop bar gravel bike I see has rims that are in the 22-25mm wide range and run 38-45mm tires. Seems like a common range that works well for varied riders, at least around me.
