I am microwave amateur radio operator. A friend was discussing using an
eBay purchased Trimble 57963-D for providing a 10 MHz reference.
As you stated, the time needed for position hold is significant. For my
microwave gear that needs 10 MHz in the field, I use a Jackson Labs
LTE-Lite.

It can be run in "mobile" mode. I have used it to discipline gear I run
up to 241 GHz. Most of the disciplined LO's are Axtal in the 100 MHz
range. It also supports 'position/hold' mode for use in a fixed position
such as at home in my shop.
There was a group buy a while back.
Frankly, absolute frequency accuracy is a bit less of an issue than it
used to be because so many of us now use SDR's for panadapters on
receive. We can "see" 48/96/192 kHz of bandwidth at once so if a signal
is off a few kHz and moves a bit, no big deal.
If you are trying to do weak signal digital modes, that's another story.
