That sounds about right, ST.  Elizabeth was always pretty much a "pass-through" lake for me.  I seriously doubt its Eastern half sees much traffic at all.  I seem to recall reports from years ago regarding passage to Halliday & through to Sturgeon that suggest that almost no one ever goes that way ( I'd certainly want to check in with park portage-clearing crews before I would ever attempt it).  Anyway, there ought to be little through traffic, so I'm guessing you're right about the solitude factor.  Regarding fishing, I would merely observe that you hear much more about Jesse.  Furtman's guide says it is a northern pike & walleye lake.  That's no surprise.  If you want lake trout & smallmouth, just drop down to Walter.
