I did the trials a couple of years ago or more -when only Amazon had the 3-month one, and I also opted for Amazon Unlimited. At the time, Amazon stopped charging extra for its HD and new Ultra HD tracks, both of which are lossless offerings. That pretty much sold me and I finally moved from Spotify, even though I had a nice and handy Spotify Connect device, and I had used the service for 3 or 4 years. I tired of the company's HD-is-coming story -and it's still where it was back then. Spotify also moved heavily into investing in and expanding to non-music offerings -podcasts; so I figured that lossless/quality music streams would be continuously or increasingly unlikely. I might have considered Tidal if it could compete on cost, but Amazon was, and still is I believe, the only company that offers a discounted annual plan, which I had always had by default with Spotify, though at the constant monthly cost. I also learned at the time that Amazon pays artists a fraction more for plays than any of the other services -especially Apple, I believe, as much as more than twice the other levels I believe.
You may want to explore how device-friendly Amazon would be for you. I use it on Windows 7, 10, and 11 platforms, plus on Android portable devices, but we're talking Amazon, and I'm sure it's more versatile/adaptable than that.
As for your bluetooth question, in my experience, wireless is always a compromise, though the differences are not as great as they once were using technologies such as LDAC which is what I prefer and use where I can and as necessary. Sorry that I don't know the limits or capabilities of your devices. Enjoy your listening on your eventual selections.
