I used 2" blinds for the reasons you state, and while they function very well, they are a pain to dust. The white ones don't show dust as much, the mahogany ones always look dusty.
I don't care for the vinyl or aluminum ones, though they can be washed when they get grungy. Mine are wood, not faux wood, I suppose you can wash those if you have string ladders instead of tapes.
Fabric rollers block your view but are low maintenance and good for privacy. I have them in guest rooms, and wish I did in the master bedroom as well. Woven woods do lovely things to the light if unlined, but aren't great for privacy unless lined. I don't think solar will give you enough privacy in the bedrooms, but I've never used them. Cellular work well and offer some insulation, but I'm not sure I'd used them in my traditional space, and they do block views.
There doesn't seem to be a really great solution that covers every need, does there?
