secure and fast alternative for windows better to switch Trisquel 11 ?

Hi everyone,
Since Microsoft is ending updates for Windows 10 next month, I’m looking for a secure and fast alternative. My system can’t run Windows 11, so I need a Linux distribution that’s reliable for simple browsing and online purchases (e.g., IPTV services like https://primestreamly.com
) and sites for browsing etc..

I don’t need heavy software just something lightweight, safe, and quick. What would you recommend as a good distribution for this situation?

Thanks in advance!
