Which would you choose?
- A perpetual license, locked to a specific software version
- A perpetual license, with free updates forever
- A perpetual license, with a side-car support contract (for updates and help)
- A subscription license, with continuous updates, as long as you keep paying
Depending on the editing software you choose to use, you will be in one of these camps.
You Get What You Pay For
Financially, using FCPX or DaVinci Resolve - with their one-off payments and free updates forever - makes the most sense. You pay once, it lasts forever.
If you stop using them, it doesn't cost you anything, and you can always open an old project and stay on track with new improvements and feature additions.
However the 'majority' of the industry use Adobe Premiere Pro or Avid Media Composer.
Premiere Pro users are locked into paying for Adobe Creative Cloud till they can't take it any more, and woe betide you should you want to open an old project without an active subscription.
(Maybe export an XML of each sequence as part of your mastering deliverables to be on the safe side)
