I just edited an old meme, but lucidchart which I use for work has a floor plan tool available in the free version.

Microsoft Visio has floor plans as well, but it normally costs money unless you already have it from work or school. There’s a site called smartdraw, also costs money but has a free 7 day trial.

Afaik proper architects use AutoCAD, but that one’s way expensive.
