Use the filter.... You probably are seeing more image quality loss due to the "do-it-all" 28-300mm zoom lens, than you would to a lower quality C-Pol under most conditions.
Since it's probably an uncoated or single coated filter, be sure to use a lens hood. That will help.
But a high quality, multi-coated 77mm C-Pol isn't
necessarily all that expensive, especially since you shouldn't need a pricier "slim" filter for that lens...
$73... B+W MRC C-Pol (8-layer coatings)
$79... Formatt Hitech Firecrest (slim)
$86... B+W F-Pro HT Kaesemann (16-layer Nano coatings)
$98... B+W XS-Pro HT Kaesemann (slim, 16-layer)
$99... Breakthrough X2
$129... Nikon C-Pol II
$135... Tiffen Digital HT Multi-Coated
$140... Marumi EXUS (slim)
$150... Hoya HD2 (8-layer coatings)
$154... Sigma WR (water repellent)
$156... Hoya EVO Antistatic
$200... Hoya HD3 (16-layer Nano coatings)
$200... Heliopan SH-PMC
$204... Rodenstock HR Digital
$210... Singh-Ray LB Neutral
$280... Heliopan High Transmissive

The Marumi's are very good and much cheaper than the high end, Hoyas, B+W's, etc.
No, they aren't cheaper. See above (current prices at B&H Photo in NYC). B+W, Breakthrough and Formatt/Hitech are all pretty equal to Marumi and cost considerably less.
Same with Hoya... they are also among the more expensive, for filters of equal quality. While Marumi only makes one grade of filter, Hoya makes about half a dozen. Some of Hoya's lower grade C-Pol are cheaper than B+W, Breakthrough and Formatt/Hitech. B+W also makes some lower price, single-coated or uncoated filters that use aluminum frames instead of brass.

Why not use the appropriate adapter ring and move it to the other lens when needed, or is the diameter of your B&W too small for the 28-300?
The Nikkor 28-300mm uses 77mm filters, while the 200-500mm uses 95mm... using the 95mm filter with a step ring would be
very oversize on the smaller lens.
The main reason to
not use a step ring is because you typically cannot use a lens hood when the lens is fitted with an oversize filter, and the lens hood is typically more important than any filter, protecting the lens from oblique light, as well as from bumps and hard knocks.

Using a 77-95mm adapter ring will be somewhat unwieldy - and no hood possible either - unless you buy a 95mm round metal and screw it into the polarizer ?? .....
Agreed... And good luck finding a screw-in hood that's a very good match to a 28-300mm lens. It's not difficult to find a nice deep hood for a telephoto-telephoto zoom or shallow one to work with a wide-to-wide zoom or a pretty well matched one for a prime lens. But for lenses that are wide-to-normal-to-telephoto... it can be hard to find something that will work well.
