I recently purchased a canon R10 and it came with an RF-S18-45mm. It’s decent to start but I find it lacking. I’ll be traveling to Zion National Park in a few months and want to get insight to which lenses would be best. I need more zoom. I would like something like an 18-150mm. I’ve seen some sigma lenses as well. Not sure what else to consider.

If you can afford a 3 lens kit, I think both the Sigma 10-18 f/2.8 and the 18-50 f/2.8 are quite decent options. As a telephoto zoom you might also consider the Canon RF-S 55-210 f/5-7.1 STM.
Zion is a lovely park and there a good opportunities for shooting everything from ultra-wide angle to moderately long telephoto shots.
If you mean 18-150 in FF terms, then look at the 24-105 non-L or the 24-240 as they might be close to what you like. Both of these are better than their reputation especially the 24-240.
The 18-150 is a spectacular do-it-all lens for the R10. For landscape superwide shots you may want to pick up the excellent canon 10-18mm as well. The 18-150 is a bit short for a lot of wildlife, so if that's your intent then the rf 100-400 is also a great complement.
Either way, for landscapes in Zion, you'd likely want a compact travel tripod as well, but not strictly necessary. But get that 18-150, it's spectacular.
The folks suggesting the sigma f2.8 zooms are pointing you towards "fast glass" but for outdoor use you don't need the speed, you can put your camera on a tripod or use stabilized lenses. Those sigma lenses make for a nice indoor set, or for street photography, but for your uses, the 18-150 rocks.
My two cents: I own an R50 as my knock-around camera. I was so surprised at how well the 24-105 STM pairs with that camera. I own the Sigma 18-50 as well because I did not like the build of the RF 18-150, and I don’t tend to go past 100mm in my photography. The Sigma lens pairs beautifully, but I need to be careful with the control ring, which is right next to the camera body.
I lived in Northern Arizona during my film days. I wished I had a wider lens at that time when I traveled to Utah’s national parks frequently, so I like Steve, Jake, and Jim’s suggestions.
Especially for travel and outdoors, the R10 plus RF-S 10-18 and RF-S 18-150 are a compact, lightweight and capable combo. The RF 100-400 is the ideal addition for long range. None of these lenses is “fast,” but can give excellent results in decent light with the R10, and each is Image Stabilized, which makes up for the R10’s lack of IBIS. Just my 2 cents based on my own experience with this combo.
Agree with the posts above, the Canon 10-18, 18-150, and 100-400 make a pretty complete package for the R10. The 18-150 is <= f5.6 up to 60mm so not that dim. It focuses very close and quite sharp across its range, as are the other two lenses. I also have the two Sigma f2.8 zooms which are nice lenses but don't have IS. I use the 18-50 for indoor events relying on my R7's IBIS. I've compared all these lenses on the R7 all are very good optically. If you feel you need a fast lens you might consider one of the Sigma primes, they come in a variety of FLs. But start with the 10-18, 18-150
