How about the MSR Trail Lite 1.3? It looks like it's just a smidgen larger (1.3L) than your target specs but it's close and wider than taller (5.9" wide, 4" tall) https://www.amazon.com/MSR-Trail-Lite-1-3-Pot/dp/B07YY1PHT5 The strainer lid is a nice feature which would allow you to strain pasta.

If a 1 liter anodized aluminum tea pot could fit the bill I would recommend the GSI Hallulite which is wider than it is taller and is what I enjoy using.
