Practicality of SDR-based TX/RX

The advantage of option #1 is that there's usually an amplifier built-in which provides a decent amount of power output. Most #2 solutions would require an additional device to achieve a similar state....

Practicality of SDR-based TX/RX

I think you're over-estimating the flexibility of SDR for transmitting on ham bands. SDR may simplify modulation from a hardware point of view, but transmitters for most bands and modes require ...

"Remote" two-wire PTT and audio for rig

A fair number of base radios can function as a cross-band repeater. If this is the case, and your local regulations allow it, you might not need any cable or gizmo at all.
