Could be "LEO WiFi" or... Is there an airport nearby? Could be a
locale marker.

I see 6 coax cables up there, I'm guessing a Cell tower, with 3 or 6 directional antenna.
Must be high frequency, but I can't tell the size from the perpective
of the pictures.

Major airport 5 miles. This isn’t directly in the landing path, kinda off
to one side by a couple of miles.

Nope. Much too small an antenna. 6 coax cables means 60 degree
sectors, which makes no sense for a suburban low altitude antenna.
Cell user driving by would end up having to switch sectors several
times. It might be DAS except that DAS antennas usually use big fat
heliax coax cables, not something that looks about the size of RG-6/u.
It's also not a beacon antenna, wi-fi antenna because of the high loss
coax, 4.9GHz police communications, or something similar, mostly
because of the 6 coax cables.
Those 6 cable also beg the question of where do they go? Following
the coax down the pole, it goes into a long conduit, exits temporarily
just above the power meter, and goes back into a different conduit,
which disappears into the ground. So, where's the transceiver?
Certainly not in the antenna, which is much too small. Certainly not
buried in the concrete sidewalk with no evidence of a utility vault in
the sidewalk. Even so, the coax cable loss would be too at cm and mm
wave frequencies.
However, the killer is the "radome". If you look at the bottom edge >carefully, you'll see that it's very thin, which makes it metal, not >fiberglass. Metal covers make rather poor radomes. The paint color
is also fairly common for metal covers, but not for radomes.

(Insert drum roll please). My guess is that these are RG-6/u or
RG-11/u CATV coax cables running to various businesses on the street.
They are terminated with a power divider or possibly an amplifier,
which might explain the presence of the power meter on the pole.
Although an odd place to terminate CATV cables, I guess(tm) someone
did it to keep curious engineers bearing screwdrivers from taking it
apart.

It's a short range cell tower common in industrial areas of Silicon
Valley. Those are likely power and networking cables sticking out.
Very nicely done. Nothing like that in Santa Cruz yet. I have my
doubts that anyone would install a 60 degree per sector antenna that
small with 6 very long coax cables possibly going to a nearby
building, but it's possible. The RF hazard sign is the clincher.
However, what is inside the 4 boxes hanging from the pole? Telco
backhaul?

I'm not sure what the slender metal box is. Batteries?
A better question is why you didn't read the sign on the other side of
the pole?

Could also be non-std comms for the local transit company.
In SD are the rail line and bus line had repeaters all over the place.
It was called something or other 'mesh'.

Is it a Comcast (or some other) neighborhood hotspot? There's one at
the end of my street - not at the top of the pole and not so many wires
but it's similar in appearance.
See if it's on the map:

So what does the sign say? Your eyes are a LOT better than mine if
you can read that.

Looks like you may have nailed it Griz:

Verizon wifi.
That’s the exact location.
Could be a diversity array.
You guys may also have missed that it is not merely the stub on top
with the coaxes going into it., but the two foot plus pair of sticks
below it with the little short knobby nipple sticks under it as well.
Maybe it is modern carbon fiber shell material. If it is a radome it
cannot be metal. Use some common sense.
The coaxes go into a very large conduit next to the power meter., but
why a two foot section of the bundle is exposed is a bit confusing.

You may be correct but I doubt it. I've seen that radome before and
my guess is that it's part of a mesh-based automatic meter reading
network. or AMI (automatic metering infrastructure).
If it is a mesh node then it's most likely just a frequency translator
with the "box" being somewhere out of the photograph.
