Dude don’t cheap out on cans, you’ll never be able to sell them and they’ll be expensive paperweights when you have to upgrade them down the road because they suck. Ask me how I know.
My advice is always to buy the best can that’s on the market at time of purchase. A $200 tax stamp and up to a year weight are damn good reasons to buy once cry once.
If money is an issue right now you can always get a 0% credit card that will give you 12-18 months to pay them off too.
The best can currently on the market for a 556/6.5/300BLK combo is a Dominus-SR. The best 22 cans on the market is a toss up between TBAC takedown and a Q erector. The best 9mm can is unfortunately still the Ti-rant but it’s an AAC and their QC is trash and if you find one in stock who knows if you’ll have a warranty since Remington just liquidated them. If I was buying a 9mm can today it would probably be a Silencerco Omega 9K but they have their issues too.
So here’s my advice. You could get a 9mm and 22 can and buy top tier and stay within your budget and probably find them in stock. You can get a 50% off TBAC certificate off here for $200-$250 or a 100% off for $800ish and then order your rifle can. There’s a pretty good backlog on them and TBAC doesn’t take payment until the can is made so that gives you time to get the rest of the cash together assuming you go the 50% route. 100% certificate would have no payment due of course.
I agree with your "buy once, cry once" reasoning. But there really isn't any such thing as a "best" can in any given category. Every can is a compromise.
The Dominus is a fantastic can, as long as you're willing to commit to TBAC muzzle devices. If you want to standardize your muzzle devices so you can move suppressors from different manufacturers between your rifles, you'd be much better off going with something that uses the Omega thread pattern, like a Dead Air Nomad (or even a YHM Resonator Gen2). There are lots of great rifle cans that could be considered "best" depending on someone's priorities and use cases.
The reigning king of rimfire cans is the Dead Air Mask, the only reason to get anything else is if you want lighter weight (which I'd recommend for pistol use), or modularity (don't bother). I'd recommend most people avoid aluminum rimfire cans because of the limitations on cleaning options, so if you want lightweight, go titanium, something like a Q El Camino, or Energetic Armament Nyx Mod 1.
For a pistol can, the Rugged Obsidian and CGS Mod9 are generally considered the 2 best options at this point. The Omega 9K is too fat to work well for handgun use, but does make a decent PCC option (also consider the Dead Air Wolfman, and YHM R9).
The cans you listed might be the best options for you, but they sure wouldn't be for me.
