Sell Me Your Women, Your Children, Your Vintage Turntable...

Taste is idiosyncratic, but ...

Do you need a suspended table? You do unless your floor is a concrete slab far from a freeway. If you don't need a suspended table, don't pay for it. Like my choices. 

Air bearing is mine. Once you've heard air, there's no going back. IMO. Sometimes used air bearing TT come up.

An alternative with exceedingly quiet bearings and low motor noise is Nottingham Analogue, which I also own. NA doesn't have much presence here, so you may need to go to the factory. NA doesn't advertise nearly as much as some - but, do you want to pay for advertising or quality product? Occasionally a Dais comes up used.

For tonearm, consider the Trans-Fi Terminator air bearing tonearm, which IMO is the best buy in high end at about $1k, and competes with anything costing less than a new car.

For cartridge, wait until you've sorted out everything else. That's what has worked for me. YMMV

Interesting assertion. Let's deconstruct.

First, can't do the test you recommend because I have ESL's, but I am confident that it would disconfirm your assertion.
Second, environmental rumble is obviously a function of environment. The most usual source is traffic. I specified, "far from a freeway." Perhaps I should have added "railway" and "volcano", but thought that "freeway" would stand for all.
Third, vibration does NOT travel through everything. Proof: since your Sota TT is a thing, and you say that vibration doesn't pass through it, vibration does not pass through everything.
Obviously it is a matter of degree. Here a high mass TT is useful, while a suspension with its own resonating frequency may be a liability.
Fourth, it would seem that ambient sound would only vibrate the tonearm if the frequency were right, the shape were right, the effective mass were low, and the volume were high.
That's an argument for a high mass tonearm and cartridge, rather than a suspension with its own resonating frequency.

Or so it seems to me.
