Hi don and others tonight:

typical historical finishes

Walls----

kitchens--beaded vertical or horizontal wide pine boards topped with a nice molding--boards could be washed with a red ochre paint stain--no additional sealing--above this wainscoating just the plastered wall surface usually left the lime white until such time as it needs refreshening, then maybe paint would be in order

floors----

wide 1.25|" thick t&g pine boards surface nailed, sealed with cedar oil yearly to harden the surface
