Is there any other difference other than the number of rounds someone would need to give for system design at interviews of these levels.
Okay, this is actually an easy question (unless I'm super out of the loop): Junior engineers generally don't get system design rounds.
If a company is giving a true, in-depth, rigorously graded system design round to a junior engineer, they are being cruel and have outrageous expectations.
You can go through my entire L3 -> L4 course and see there's no mention of system design: Grow From Junior To Mid-Level Engineer: L3 To L4
I was at Meta, and juniors [E3] at Meta are like mid-level engineers at other companies (they're paid like it too). Despite that, I would never expect an E3 to be able to do high-quality system design. That is so unreasonable.
I see for mid level roles they have a system design round, how would that be different from the ones for senior level. I find that system design is really wide. Wanted to understand for a mid level role interview how much is required

My bar for mid-level is if they can just do a non-embarrassing system design at all. It's tricky to quantify as system design is inherently quite fuzzy. This should shed some color on what senior looks like: "What is the difference between a Senior and Staff engineer in a System Design Interview?"
I recommend the technical part of the L4 -> L5 course as well: Grow From Mid-Level To Senior Engineer: L4 To L5
