Which should you buy?

Architecture, Landscape & Astrophotography — RF 15-35mm f/2.8L IS USM (2019): The best wide-angle zoom Canon has ever made — optically superb, stabilised, and L-series built.

Compact Travel & Content Creation — A7C (2020): The A7C proves full-frame doesn't have to be bulky. Excellent battery life, reliable Eye AF and a vari-angle screen in a pocketable body is a compelling combination for travel and content creators. The A7C II improved on it, but the original remains a strong value buy.
