Lens choice is tough .. and personal.
I used to carry the 17mm to 400mm trifecta ... and some primes. My back and shoulder and legs felt it.
Once I switched to F2.8 16-35mm + 70-200mm (and no primes) my back didn't feel any better but I could fit stuff into smaller bad, so traveling got easier.
Used to carry a full tripod, but found one of those minipods enough for most cases ... just find a taller rock, not perfect, but works.
Then I downsized to m4/3 and super zoom ... yeh low light sucks, yeh autofocus sucks, basically no bokeh, but damn, I didn't feel the camera on me at all .. I could hike further and higher up, walk longer, be less tired at the end of the day and so be happier when traveling ... (note modern mirrorless are lighter already so might not be as much of an issue).
I know people travel with single 24mm or 50mm or etc .. and are perfectly happy because that's the look they go for. It's tough to know till you try .. and when you do get only one lens kit, you will certainly hit times wishing you had more lenses .. but less so than times you wished you carried less if you carried all the lenses all the time.
I'd recommend starting with 24-105mm/equivalent .. F4 for lighter travel. See if 24 is wide enough, and 105 is long enough .. and go from there. F4 with modern cameras is often plenty as ISO perf is really nice. If you want bokeh, get a nifty fifty. (or blow 3 months rent on RF F2 zooms!)
Then if you find yourself using mostly wide end .. just try carrying a single 24mm .. if you're all over the range .. consider just 24mm and 100mm.
I found I could never give up the zoom range, so I gave up F stops and iso perf. Many people chose differently and want clean images or perfect bokeh.
Experiment, no one can really tell you what you want, like with knives.
Photography is often about the experience and overcoming challenges, so not having the perfect lens is just an encouragement to think differently.
edit: ps: if you get a tripod get a light one, otherwise you're not going to take it with you most of the time .. and get a good one, Manfrotto / Gitzo etc, cheap stuff will sag, ruin your photos, brake and/or be annoying to use .. so you won't use it anyway.
