Bikepacking - a viable alternative to racks & panniers

I haven't yet decided about shoes though, as they are also bulky and might be heavy.

If you're happy with it, clip and strap with normal shoes would work perfectly well, meaning only one shoes to walk and ride, and I was glad to have it when I was touring, except on fixed wheel down the Pyrenees that is.

Or go for touring/mtb shoes that you can walk and ride, but it's more of a jack of all trade master of none kinda shoes.

The other option is the Timberland Radler Trail shoes, I have them and they work great, but a bit redundant after going back to clip and strap;

Teva Mush Frio is another option, tiny bit heavier, but very plushy and comfortable, can pack small in a saddlebag, look a bit "special" thought.
