Lanai has eastern exposure so no direct afternoon sun.
Suggestions/opinions?

Double pane, with argon gas, provides good insulation, easy window washing and hurricane wind resistance. Single pane generally has one screen, where our three door sliders have two - single screen makes it hard to wash the outside of the windows. Being west facing, we still needed a shade for afternoon glare. Sound deadening, which is very good, was not a key feature for our installation. We're very happy with Custom Window's double pane solution at roughly $600 per linear ft. (2019 prices).
We chose a mini split that included both heat and cooling. Set a temp level and leave it alone all year (we also chose to spend more for the flush mount ceiling unit). Yes, the Mitsubishi mini is very expensive but it's essential to our daily use of the lanai. Munn's did a great job with the installation.
Slightly off issue - there is no insulation above the lanai (or the garage) so if you're enclosing and cooling, that will need to be addressed. Solar Guys will blow in insulation for a reasonable cost.
