What color furniture is good for red doors and yellow floors

The easiest color to match with red is white, which can make red more conspicuous;

Yellow can be paired with light yellow + lavender, beige + ochre or cooked brown, medium yellow + olive green or other green & black that is not too jumpy, earth yellow + white & dark red, dark yellow + lake green & blue.

Depending on personal preference, generally speaking, the floor makes the whole decoration account for a relatively large proportion, mainly to highlight the floor, so the yellow collocation is the main consideration.

It's the kind of dark coffee, like the feeling of a dark solid wood floor, which is what my house is

I'll give you a rendering for your reference.
