I use a pull-down honeycomb shade with a basement window that's behind my TV:

It's a total blackout, though it definitely benefits from the window being deeply inset; on a typical bedroom window at midday I expect a bunch of light would find its way around that.
I got something similar (amazon yoolax blackout cellular honeycomb shades). They have extra help from L-shaped side panels blocking light along the sides.
bedroom is ultra-dark, with just a hint of light.
Those are pretty slick, will check those Yoolax ones out, have manual versions from Ikea that work well for both temperature control and light control.
