West coast itinerary recommendations

Landing in San Francisco on July 5th around noon and need to be in Las Vegas by July 11th afternoon. First time doing the West Coast and planning to rent a car + drive.
I definitely want to spend around 2 days in LA (Santa Monica, Malibu, WB Studio, general touristy stuff) but trying to figure out the best route between SF and Vegas.
A few questions:
Is July too hot/unpleasant for Sequoia/Yosemite?
Is doing both coast + national parks too ambitious in this timeline?
Would you recommend:

SF → Monterey/Big Sur → LA → Vegas
OR
SF → Yosemite/Sequoia → LA → Vegas

I enjoy scenic drives, pretty towns, cafes, viewpoints etc more than hardcore hiking. But since it’s my first West Coast trip, I also don’t want to miss out on a major national park if it’s truly worth it.
Would love realistic recommendations on pacing, where to stop overnight, and whether I’m trying to cram too much in 😅
