Now here's where it becomes difficult to decide on which way to go when it comes to comms, 99% of the terrain in the our neck of the Pacific NW is dense forest, mountainous and repeaters are pretty much non-existent (100+ miles).
In these scenarios will HAM be of any use or are we stuck with SAT?
It's pretty important to know the infrastructure available, and it's use-levels. From the sounds of it, both of those factors score low in your intended area. Lack of good repeaters (stable, good coverage) with people actually using it (monitoring or actively chatting) can quickly make that route a dead end.
HF is indeed an option, but unless you intend to nerd out on it, it's not something one should reasonably expect to be able to put into action in times of need. Not to mention the sizable antenna needs which are rarely conducive to off-road travels. Even ignoring the need for practical experience and antennas that like to reach out and grab tree branches, it's still difficult to know where in the bands to go and who will be on the other end. (Do you really want to try to get some random guy in Indonesia to send help to you somewhere in the middle of Oregon?
As others have said already, more options are ALWAYS a good thing, but as an extra-class ham myself, I only consider it one tool in the toolbox. For that reason, my Inreach SE goes with me if I'm likely to be out of cell signal coverage.
That said, it's possible that that one tool may be the life saver. I had an incident some time back when a friend who was with me on a backpacking trip got separated and despite my fat *** making it back to the vehicle, he was still MIA hours later despite being a much stronger hiker. A big storm was rolling in and eventually I made the call to get some assistance. Called out on CB (more to stall in hopes that he would show up before I had a S&R bird hovering in the area) and was not surprised when that led nowhere. Called out on various ham simplex frequencies, including ones often used by the AZ off-roading community, nada. (50 watt mobile radio.) Scrolled through and realized I wasn't even receiving DPS chatter in that area, so no point in shouting out on their freqs (not to mention almost a guaranteed 'adios' to my ham license.) Finally went through every repeater programmed into the radio, kerchunking and failing, until FINALLY hitting a machine in Flagstaff. As luck would have it, my call out was answered by a local who used to even live in the area I was in. He relayed to the authorities and the ball was rolling.
Not 10 minutes later my friend emerged from the forest soaked and less cheerful than usual, so I was able to call off the hunt before anything even got started, but it was still a case of ham working for that particular situation and location. Had that one repeater not worked, I would've had to abandon the agreed-upon rally point and made my way back towards the highway and civilization until I could reach someone, and it would've turned into a cluster****. Having an Inreach would've been a phenomenal tool to have handy to escalate to.
I've also been in canyons where even that wouldn't work without crawling up some rock walls to get a view of the sky, so grain of salt there.
I may have skimmed this thread too fast but although I have a job and can afford most essentials, I missed ANY mention of an economic reality....
3) Ham Radio - go to class (often free), get a license ($15 fee) and a radio ($29 - Lots depending on how much you want) and go for it....
Small nitpick here, but ham licenses do not actually cost $15. $15 is what the ARRL currently charges to administer an exam. The FCC, however, has zero fees for new licenses and renewals. (Vanity callsigns do cost a few bucks though.)
The ARRL is only one of over a dozen VEC (Volunteer Exam Coodrinator) options out there. They ARE the most popular and easy to find though.

Laurel VEC charges $0 for the exam, so it's worth checking to see if they have any teams in your area. They also process results a lot faster than the ARRL, which means your callsign will likely be in the FCC ULS a LOT faster. (It's not guaranteed by any means, but anywhere from the next day to another day after is very common.)
Disclaimer: I've been an ARRL VE for years, and was briefly lucky enough to work with Laurel as a VE as well. Both are great groups of people and cost aside, you can't go wrong with either.
