May I suggest to try replace npm (and npx) with pnpm. pnpm (and pnpx) has a better cache system than npm. With pnpm you only download a version of a package once and can reuse it in several projects. In theory the slowest installation of create-react-app should be the first one, after the cache has all the packages that you need everything should be way faster.
You could also try one of these tools
parcel: here is a guide on how to start with react using parcel.
