Solder selection for general repair work

At long last I've completely run out of solder for electrical/electronic
work. Last time I looked, Kester 63/37 or 50/50 were the norm, with a
choice of rosin or acid flux. Things have changed a lot since then 8-)

Now there are dozens of brands with at least as many compositions.
Usage isn't very high, so a "do it all" alloy is preferable. Cost
is probably of secondary importance.

Anybody got a suggestion for a composition and brand? Amazon shows
quite a few, none of them familiar to me.

Thanks for reading,
