Only you can answer that! It's a personal thing. It's subjective. It's a science.
What works well for YOU, might not work for others.
Lot's of experimentation and trial and error is in order.
If you stick with lifting for a long time you'll have tried many different splits, combinations, rep ranges, intensities, etc.
When you find something you like, don't be afraid to try something else.
I tend to change my routine every 4-6 weeks.
I also don't like to have set days like Monday is this, Tuesday is that, etc. Instead, I go by workout 1, workout 2, workout 3, and workout 4. And the frequency varies. It depends on how I feel. I might hit the same muscle group every 4th, 5th, 6th, 7th, or 8th day. Depends on the volume / intensity / recovery.
For the routine you mentioned, I might do this:
Monday is chest and shoulders cardio
Tuesday is back cardio
Wednesday rest
Thursday arms cardio
Fri legs cardio
Saturday and Sunday is rest day.
