How much is the OP planning on spending for the remodeling?

How much are they willing to spend to prevent moisture troubles?

30K for remodeling?

Do the interior french drain to sump or preferably dalight outside so
you DONT need a sump pump, and back up sump pump in case of power or
pump failure. Gravity is very reliable!

Look I have been all thru this, spent 10K digging and installing
outside french drains, new sidewalks, regrading yard, landscaping. I
did a lot of the work to save bucks. After that water still in
basement

Moisture enters ion many ways and as others have said you CANT stoip
it just redirect it somewhere else.

the interior french drain is the ONLY way to go!

then clean walls, drylock them. let sit awhile to fully dry.

then do your remodel.

install basement ingress egress windows, to increase home value, you
can then call it a bedroom more money at resale
