Vegas to National Parks itinerary recs/help

Relatively new to the National parks life and would love your recommendations!

Moved to Vegas & want to take advantage of long weekend trips to the national parks nearby!

A few 3-5 day itineraries I had in mind -

1. Death Valley & Joshua Tree (do you recommend combining the two or separate trips?)

2. Zion & Bryce (should we add Antelope Canyon here?)

3. Grand Canyon (& maybe Antelope Canyon?)

Thinking about other parks like Capitol Reef, Moab, Arches, etc - not sure what might be the best itineraries !

Any feedback/recs welcomed!
