Funny, I had valve ticks and weird rod-knock type noises with 0W20 PP in my 2013 3UR-FE. Being a Toyota that what their VVTI systems sound like anyways, it's really tough to tell, and and my TechStream said the knock sensor didn't move the timing back, so it was "within spec" as far as the ECU was concerned. That stopped when I happened to pick up 0W20 Castrol Magnatec on clearance and used that, which was unexpected.
OP - whatever the Toyota viscosity for the vehicle in a good synthetic, and Denso filters, you'll make a 10k/1 year OCI with ease. Fram Ultras or whatever if you can get them for a price close to the Densos, but super-duper filtration isn't needed for any 21st century Toyota I am aware of. Test then, you might be able to go 12k or more even without going with M1EP.
