I need to see the windows IMO 60" wide blands are often too wide and do not operate perfectly over time. Waht kind of blinds ? More info please and add it to acommnet on this post no new post.

Roller shades - motorized were suggested with wifi hub to control with google home or app

I think either one or two will look odd when not lowered. You should go to expense of getting three: one for each section of the window.

I asked for 3 and I was told doing so would create more gaps between the blinds and let more light come in

I spoke with my blind designer, it turns out my wall to wall measurement is actually 135-140 inches.
I could do 2 blinds with one blind covering two windows and second one covering the final window, or can do 3 blinds with each one covering one window.
She warned that doing more blinds would also leave about an inch gap between them.

How wide is the metal trim between the windows?

It's about 2.5 inches.
Also what do you guys think about 3% solar shade material, my designer said as I have a great view, thats the best option for living room.
But then as you can see it gets really sunny in my condo, so not sure if I should switch to 1%?
