We are building a new home and need to outfit about 25 windows. For most rooms, we are thinking cordless lift, wand tilt, faux wood blinds. Cordless is a must as we have young kids + cats. All the windows are trimless but with sufficient depth to inside mount the blinds. The windows are mostly 36"w x 63-72"h, for a general idea of size. There are a couple of rooms where the windows are doubled up and we'll use a single wide blind (no need for a 2 in 1 rail). I know they may be heavy, but we will rarely lift them in those rooms.

The Bali cordless 2" faux wood blinds we bought for our current house 7 years ago are routed through the center of the slats for the stringing, and those holes let in a decent amount of unwanted light...especially that one piercing beam that finds the corner of your eye while you're trying to watch TV in the evening. It annoys me to no end, and I was excited today to discover a couple brands online claiming to have routeless AND cordless blinds, sold under various names including Veneta, which shows up on both blinds.com and Home Depot. The brands I've seen so far all describe this as "SmartPrivacy" (trademarked). I think the trick is there ARE small holes drilled, but they are near the back edge and are covered by the slat overlap when closed. They aren't like the more common corded routeless blinds that have little grooves along the edges that struggle to keep the slats in place.

Does anyone have experience with blinds with this feature to speak to its effectiveness, or to suggest brands or storefronts I should consider or steer away from while looking for it? Are they just all the same company operating under different names? Any alternatives to this design that I should look into? Though I measured, ordered, and installed the custom Bali blinds myself, I'd prefer to order through an easy measure/install service this time given the large number of windows and current time constraints around work/moving.

Oh, and while I'm here.... would you go for 2" or 2.5" slats for my window sizes? I was thinking maybe 2.5" makes more sense given how tall they are and that I've got the window depth to fit them. Pic below is the sunroom... the rest of downstairs is 9ft ceilings with the same 3x6ft window size. The builder-grade sheet vinyl and carpet will be replaced with a warm medium-toned wood LVP throughout.
