That Adafruit Ultimate GPS Breakout works quite well indoors. I live in
an older house with tongue & groove roof topped by slate and plaster &
lath walls with thick stone on the outside. That GPS usually has 8+
satellites anywhere in the house except the basement. Basement not as
good, often no reception at all.

I'm looking into a TU36-D400-020 receiver.
What antenna to use? I would prefer something mounted inside the case. It
is wood so an internal antenna will hopefully work. The board comes with a
pigtail but it is not SMA.
That's an old receiver. Modern receivers are much more sensitive and much
more likely to work indoors.
I suggest getting a modern chip. Some of them come packaged with an antenna.
Then you can play around with it from a PC, arduino, or Raspberry Pi to
figure out what you will have to do and how well it will work.
Here is one to consider:
Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz updates - Version 3

If you have room on the display, you can display the offset between the time
as derived from GPS and the time from the power line. :)
