Ideal for what? There are too many variables so you weigh the pros and cons, pick something and practice with it a lot more than you think you need to.
Anything from a 9mm to a .458 Socom could be ideal for some set of parameters. I am comfortable with my choices given my variables, knowledge. skillset and practice regimen.
There are some answers in this thread that I would argue are poor choices and others I would agree are good choices, for the best balance of pro and con. But I will also admit that my personal choices have changed based on changes in my set of variables. For instance, I got rid of my .380 pistols for SD and my magnum rifles for hunting so I have essentially loped off the ends of the spectrum.
Someone mentioned "suppressed"...if that is an option for you, suppressors are a good idea and mitigate some of the downsides of higher pressure cartridges indoors while adding a little weight. They do even better with PCCs.
