Should I replace my Sony A7IV for a Lumix S5IIX?

I'm a beginner in videography, but a friend of mine insisted on me shooting a video of his band playing live in his restaurant. For that purpose I got an A7IV with a Samyang 35 T/1.9 and Tamron 28-75 F/2.8.

Investigating further I found out the S5IIX is both cheaper, newer and has more flexibility for video. I guess that there are fewer lens options.

I'm looking for opinions/discussion. Thank you so much.
