This will be personal preference, but I’d recommend you hang onto both of those for the moment. You’ll find the 27mm hose is quite a lot more convenient to use with tools that don’t need anywhere near the maximum suction the vacuum can provide (sanders, track saw, drilling, etc). There’s a reason that it’s the default hose: they’re not just including it to be cheap. For work of this kind, you’ll also find the long-life bag will save you a lot of money in the long run over using replaceable bags, particularly if you don’t have a cyclone attached to the machine. Long-life bag + direct 36mm hose attachment is still going to provide you better suction than disposable bag + cyclone + 36mm hose, if that’s what you’re interested in.
But remember, for the vast majority of power tools, the suction of this machine is way overkill. You have to turn it way down when sanding unless you want to leave swirl marks all over your work surface. The last and worst-performing configuration I listed in my airflow test chart is actually the one I use day in and day out! I’m giving up 45% of the vacuum’s actual airflow performance and don’t care because what’s left over is still plenty strong for the tools I’m using it with. The only times that I switch things around for better performance are when I’m using heavyweight tools that throw off an enormous amount of material: the HL 850 planer, the OF 2200 router, and the Kapex. In those cases, I usually bypass the cyclone and go direct to the vacuum because the extra airflow really matters. For the router and planer, I’m using the 50mm extension hose that comes with the boom arm connected to the 36mm hose on the boom itself. For the Kapex, I keep a 36mm hose permanently attached at my miter saw station so I can just wheel the CT over and plug it in when I’m using it, rather than fussing with trying to position the boom. (Eventually, I’ll probably replace this with a direct hookup to the shop dust collector, but I haven’t built a full shop ducting system yet and am still wheeling machines around with hoses at the moment.)

The way I would summarize it is “it’s a lovely saw most people shouldn’t buy”. What it will give you over your DeWalt is cleaner cut quality (because of the thinner blade), better factory calibration, better dust collection, the industry’s best hold-down clamp, and the ability to butt it right up against a wall if space is a constraint because it uses a rail-forward design which only one other saw on the market (Bosch) uses. (I don’t have the mobile stand and wings for it, but what I’ve generally read is that they’re “okay”; the Fastcap wings are supposedly better than the OEM ones.)
If budget is a concern, though, these features probably aren’t worth paying 3x the price of a new DeWalt. I love my Kapex, but I also recognize it was a pure luxury purchase and for practical purposes was roughly equivalent to buying gold-plated tools for bragging rights. But I’m not a professional, and those who are may have a different perspective on it to share.
