The 100 hr pic minimum is the biggest aspect to this.
Your XC time can be converted but you still need to do a XC flight test.

Some schools mix both ways quite well , some do not.
I am 30 hours from finishing my CPL A but with 1500 hours now and
some better job prospects with helicopters.
I dont know if will use it much
