A key feature of the windows linked by the OP is the ability to vertically open them for a slight gap.

My quick search for casement windows at Lowe's (https://www.lowes.com/pl/Casement-windows-Windows-Windows-do...) didn't show a single one that has that feature.

If Lowes doesn’t have them, others will. Look for “Tilt & Turn” windows. They’re called that because they operate like a combination of an ordinary casement window plus a “hopper” or “awning” casement window.
