Any comment on Keysight 34450A continuity?

I have no issues with it(except for a brief period when it sucked with older firmware). I've never had an issue with the fan in my 34461A, it has always been quiet with no annoying high frequency component etc. It is the quietest fan in any of my bench devices.

My unit was on older firmware indeed (I got one of the early models when it came out around 2015). I have downloaded newer versions but never got to installing it until now. I have not checked whether continuity is better or not but the 34450A being slower/worse is good info.

Note that you need to update 1.x to 2.17 first, many people miss that requirement and soft brick their meter.

BTW later firmware also added capacitance measurement on shift-frequency button.

I'm not sure why there isn't more robust competition at this level.  Everyone has their own idea of what features they need and it shouldn't be that hard to just pack them all in there like they do with handhelds.  It seems like the best option to get something usable in most cases is to just move up a notch to a 6.5-digit model.  Not everyone wants 5 different meters on their bench.

I'm curious what you found that didn't work with the BK and Siglent models.  I haven't actually seen a 5492C yet but it looks like a match for what you need?  Also, the Siglent SDM3045X hacked with the firmware for the otherwise unavailable SDM3055X-E looks like a possible option at $400 in the US.

The Fluke 8808A does everything you want except capacitance--and it has a few neat additional features as well.  The continuity is reasonably quick and latching, Morse-code fast but not pin scanning fast.  The display is VFD, but it is bright with fat segments and easily visible 10 feet away in a bright room.  Unfortunately at the price they go for new or used the value proposition is not good--although not worse than the Keysight 34450A in my view.

nctnico:
The problem is that many meters have a VFD display and / or a fan. Currently I'm using a VC8145 bench DMM which is a handheld in a box. It does everything I need but the autoranging is a bit slow. And the box doesn't have quite the right size to stack other equipment on top.

I have 60, 61 (currently in whitescreen mode) and 70. I like the 60 as it's silent/fanless but Keysight have hobbled it in annoying ways compared to the 61: 3A max, no rear sockets, no trend chart (only digits or histogram), and needs a license purchase to get the ethernet functional. I would say buy the 61 and disable the fan if it annoys.
