Does anyone know of a fast, RF type, transistor? It's hard to tell
from the jillion lines of fine-print parameters.

It's hard to pick parts, discrete or ICs, from the library.
Yes it would be nice if a description of the part as well as the part number could be included.
A sortable column of Ft would be nice for transistors. Lacking that,
sorting on Vce helps spot the RF parts. Low voltage suggests RF.

Here's a circuit that includes a 5GHz ft BFR92A, which a typical
broad-band transistor. I had to put in the Spice model into the .asc
file myself.
Do tell us why. You do claim to revel in electronic discussion.There used to be quite a few of them around, but - as Phil Hobbs hasGosh, what a hideous mess, in many respects.
mentioned - most of them have gone obsolete. He has tracked down a
surviving PNP equivalent, but you won't need that to simulate ECL.

It's not the first time I've posted such a .asc file here.
