One of my favorite glute exercises with progression options are the bridge. You can do a simple bridge, then go to single leg, then elevate your legs, then elevate a single leg. Elevating your legs on an unstable surface (bosu ball) adds even more difficulty
There are other glute bodyweight exercises such as split squats. You can add a deficit or elevate your back leg to turn it into a Bulgarian split squat.
Another option are fire hydrants. This can start with a bent knee, then progressed to full leg extension, then you can add a band. Similar with glute kickbacks from a quadruped position.
Also keep in mind that you can make anything more challenging by adding a tempo and/or pause.
