Man I'm back and forth on which I "prefer" all the time. To me, it really boils down to this: where do you want to do your on-the-fly EQ adjustments? on the bass? on a pedal/outboard preamp? on the amp?
The limitation of a passive bass is that all you can really do is roll of high end with the tone knob. You can't add more "booty" at the bass beyond just adjusting the way are playing via technique, attack, etc. You can't add more mids to help "cut" through a muddy mix.
A bass with a preamp and 2 or 3 band EQ on board allow you more options as you play. For folks that want really fat and deep sounds that also want a lot of top-end bite, an onboard preamp allows them to absolute crank in sum fat bottom and sparkly string pop. The guys that love the "scooped" slap tone will often be found rocking a 5 string of some sort with a 3 band pre. Crank the bass, cut some mids, mildly boost the highs: golden. Doing that at the bass then allows more room for the amp's EQ to adjust for room deficiencies, cab strengths/weaknesses, etc.
All that being said... I pretty much never miss having a preamp on board when I'm playing my passive basses. I just play them differently, and adjust my outboard pre to account for it. At church I'm using that Trace Elliott Transit B, and it has a 5 band EQ. I also never miss my passive basses when I am playing one of my actives, lol! I am NOT a slap player at all, and am terrible at R&B. I think if I were playing those styles more, I'd be reaching for my MTD Kingston Super 5 for those gigs. That has dual humbuckers and a ridiculously powerful 3 band EQ preamp. Like... adding just a LITTLE bass EQ on that things shakes the house QUICK! It's one where I have to be VERY careful in adjusting when I'm hot in a mix. It will quickly push into clipping if the engineer doesn't already have a lot of compression on the channel or I don't have a lot of compression in the chain myself.
So I guess the answer as clear as mud. You should get an active Jazz. Or another passive Jazz.


Regarding MIJs, I think the only MIJs readily available as new in the USA are all passive. Both of my active Js were purchased from Ikebe Music in Japan and imported via FedEx. Another option is to add something like an Audere preamp to an existing passive bass. [Invalid or Expired Link Removed] I haven't done this myself yet, but have played a few with this mod and I think they're great, high-quality units. Tons of options. Tossing one of those on a $300 Squier will teach you a lot and give you a lot to play with for not a lot of coin. I have another P bass build in mind, and I am leaning towards loading it with a Musicman humbucker and a 3 band Audere, just for giggles.
Regarding the active vs passive philosophy overall, I think we're all on a unique place in that journey. Some folks have gone all in on crazy intricate active things and love it. Some have done that, only to find that the options were overwhelming and unnecessary, then coming back to a simple P bass and total enlightenment. It's something no one else can answer for you, and no amount of reading will accurately determine what works best in your situation. There is so much at play. What is your pedal, amp, sound board, speaker cab, PA, etc, situation? What is the type of music being played? Are you in a narrow range of styles, or hitting a little bit of everything? The bass itself is just the starting point in a labyrinth of signal chain and audio processing devices between your fingers and the listener's ears.
Personally, I find myself playing my passives more often at church because we kind of play within a certain range of styles. Basically adjusting my attack and pickup blend on a Jazz is about all I need to cover enough territory. I recently joined a dadrock band and we're covering a wide variety of styles. I find myself leaning towards my actives there a little more for two reasons: 1) being able to quickly get some vastly different sounds 2) using the low boost as a little "cheater" here and there when the drummer gets rowdy and I need to keep up and I don't wanna go over and adjust the amp.

Now, that second one goes out the window when we've actually got someone running FOH. At that point I just do what I do and leave levels up to them. No longer my responsibility.
Thanks very much for the kind words on the video.
