For commuting I use my gravel bike with 33mm gravel tires set up tubeless but I've also used my road bike with 25mm GP5000, also tubeless. At a reasonable pressure both are comfortable.
Gravel bike has flat pedals which is more convenient than changing shoes when I get where I'm going. For light touring I'd just put stuff in my backpack and use the road bike though.
