You could rent a VPS in a neutral country and use ssh to create a SOCKS proxy to it, then use foxyproxy to add the proxy to firefox/librewolf/whatever and either allowlist certain sites you don't want your country knowing about or denylist websites you don't care if your country knows about (especially higher bandwidth sites that aren't controversial like YouTube).
At that point you'd have plenty of "real" traffic from the unproxied websites and any traffic the rest of your OS is using, and when you access the proxied sites you want to hide it'll look like you're using ssh and/or scp.
You could also create a proxy server with a tor connection on the server and use ssh port forwarding to access it locally. The Mullvad browser + foxyproxy would probably be your best bet for using that since it's basically tor browser without tor.
EDIT: Additionally, if you wanted to proxy an application that doesn't support SOCKS internally, you can configure proxychains with the proxy and then launch proxychains applicationname.
