I found that just a resistor across the secondary pretty much cures
ringing,
at least better than capacitors across the diodes. Choose R to be as small
as possible with dissipation and transformer current in mind. With 14V~ 1k
should be sufficient for a 10VA tranny.

Yep. Same here!. And UF4001's etc for the occasional tricky-dicky, circuit
arrangements.
Wish LTspice had a realistic transformer model. A good one can be done
manually but the resulting diagram fills half the screen and looks nothing
like a transformer.
