This gets me thinking. If I was to one day peek over the Guild fence into the electric guitar yard, what would be a model to start with? All I got is the Br, and quite happy with her. No doubt this could be opening a can of worms for me.
Not this one. LOL.
There are a lot of different electrics. Coming from the Acoustic side I'd be tempted to recommend a Starfire of any ilk that pleases you, probably a II or III since they're more acoustic than, say, a Bluesbird. A Starfire IV is almost the iconic Guild electric for me and a late-90s example will never do you wrong. An X-170 is even more acoustic-like.
If you want the traditional electric Les-Paul experience, a Bluesbird nails it in every way, and just about any of them are great.
If you want the thinner kind of slab-type guitar, it's hard to beat an S-100.
Just be wary of neck size. If you're used to acoustics with larger necks, some of the vintage Guild electrics have small 1 5/8" necks that can feel cramped after years of 1 11/16 or 1 3/4" necks. That's one of the main reasons that I favor the late-90 reissues.
I would probably stear clear of anything with a floating bridge (like this one) as a first electric because the first time you go to tune it you're likely to throw it out the window and never touch an electric again.
