I only keep the Rubbermaid containers in my kitchen, the ones that are
consistent sizes so there are only a couple sizes of lids.

Food containers like from sour cream and similar go out to my shop where
they are used for temporary parts storage when I'm working on something,
of for small parts cleaning with degreaser.

Your kitchen should be held to a higher standard than reusing old single
use containers for food. Reusing them for grungy shop stuff and then
throwing them out / recycling is more reasonable.
