A static site generator (Hugo would be great for your needs) and host the files on a CDN like bunny.net. It costs $1/month for 100 GB transfer included and you pay 1 cent/GB above that. But I sincerely doubt a small personal website that's mostly text will serve more than 100 GB/month.
Hosting on a CDN is amazing because they have dozens of redundant distribution points all over the world, can easily scale to traffic spikes, you never have to worry about consuming too much CPU or RAM or about security issues etc.
