Terminus is a classic. I think it's a few decades old. I typically use it at 9pt on low DPI displays, but have gone up to 14 or 16 on large displays viewed from far away like a TV. tewi (8pt?) is another nice one. Scientifica is decent. If you need big font sizes, one of the only options is spleen. It gets rather large. I think OpenBSD uses spleen.
