Would this work or would I have problems:
Using dd command to backup an entire SSD containing dual boot Windows/Ubuntu partitions into an .iso file, with the intent to then dd that iso back onto the same size SSD in the case of a drive failure?

In general, no, this won’t work. In your case, you’re lucky since at least the Surface Go is using an x86 CPU, so it’s not completely out of the question, but transferring the image as-is to a completely different device typically does not work without modification.
Simple example: your target device might not refer to existing hardware (let’s say a storage medium) in the same manner as your old device, so the existing references in your cloned image won’t work. There are other issues of course, e. g. missing drivers for different hardware present on the target device.
It’s possible to modify the image so it would boot, but given the Surface runs Windows, that’s going to be a chore. I’d consider this an interesting project if bored on a slow weekend, but I’d most likely just do a filesystem backup of relevant data and call it a day.
I forgot to say that I’m using Linux (Fedora 40). If you think it wouldn’t work, do you know another program which would?
My data is stored on the cloud, but I wouldn’t want to go through the hassle of setting everything up again if I move to another computer (extensions, mail, calendar, installed programs and settings).
Oh, that makes everything a lot easier. The majority of the relevant settings will be in your home folder then, i. e. in the ${HOME}./.config folder, while some might also be in ${HOME}/.local/share etc.
You probably want to backup the whole home folder anyway, so that would pickup most of your settings. In order to make that work on a different system, you would have to install all applications you were using on the tablet as well. Luckily, software installation in Linux is pretty easy, so you can export a list of installed applications from the Surface and then re-install them on your target system before migrating your home folder. The software list should become part of your backup. See e. g. https://unix.stackexchange.com/questions/82880/how-to-replicate-installed-package-selection-from-one-fedora-instance-to-another for an idea of how to perform this.
I have used this approach in the past and it will get you 95% there. There might be some global system settings that you’d like to also transfer to your new system, but you can add those as you discover you miss them on the target system.
