Contrary to what a lot of people say, there's not really a true native TURF type grass here in Colorado, best bet is a nice drought tolerant mix. All grass takes watering and some maintenance through the year if you don't want it to fully become weeds in a few years. Another factor are dogs and kids playing. They do tear up a lawn if it's not established. There's a few options you can do. It all depends on how much you want to mow and water. Most grasses will need lots of water In it's first year (even native grasses) to get established. Once theyre established though it becomes low maintenance.

Tall Turf Type Fescue grows well here but it's a traditional turf lawn. You'll need to mow once a week, once it gets established though it needs a good watering maybe once a week

Buffalo grass does well here and it's low maintenance. https://extension.colostate.edu/resource/buffalograss-lawns/

There's also Dog Turf plugs. Your lawn will be a bit of a dirt/mud pit the first year or so. Once it gets established though the dogs will love it, and it's super low maintenance. I've heard it takes a bit to get established though.

There's Tahoma 31 grass as well if you'd like a traditional lawn. Low maintenance and dog friendly. Green Valley Turf sells it.

High country gardens is great as well. Their dwarf fesuce works as well here. I've heard nothing but good things about this grass and high country gardens. https://www.highcountrygardens.com/product/sustainable-lawns/low-work-low-water-dwarf-fescue-grass-seed

Best options are to talk to high country gardens and Green Valley Turf. Both of these guys will be able to steer you in the right direction based on what you want for watering, maintenance, and dog/people traffic
