Asset Sources? Buildings, Furniture and Cars?

Any recommendations regarding sources for assets? Need something like an affordable subscription service, as buying assets piece meal would just get too expensive. I'm working on a demo in WebXR (VR) so I don't necessarily want everything to be super high resolution/polygon count. This is a free demo and I have to be tight w/money rn so just trying to find a good value as I'm between contracts.

As I'm working with WebXR/ThreeJS Unity & Unreal stores are sadly not an option.

Mostly in need of buildings, interior/furniture and a few cars would be nice. Multiple LOD is a big plus as well :).

Curious what options are available and wanted to get some feedback from everyone here and their experiences. Sorry if I'm a bit rambly but I'm seriously tired.

Thanks again.
