I've used the tilt blinds kits from https://www.tiltsmarthome.com/ -- they make roller ones also but there is no (practical) integration into hubitat (for what it's worth my tilt blinds are on their own schedule and that really works pretty well)
Some people have 'cut down' the IKEA blinds to size -- results vary on that I think...
There are a number of off brand/chinese companies that make kits...
Lutron (Serena) also makes roller blinds -- those are expensive but they work really well (I have a set of Lutron/Serena blinds for the past 5 years -- great integration with Hubitat and the batteries last about 2 years)
iBlinds. Integrated into HE, working very well for me and others. Community driver as well as HE built-in. OTA updates supported. I have five, like them very much, they are working perfectly for me as of the 3.03 FW update.
