My advice would be to add the SSD via USB and give it a try. You have gone this long with what you have and still saying its "only slow at times" so Im assuming any speed boost would be welcome.
This is solid advice.
I did the same thing on older iMacs (encluding a test on my venerable G5, with an external USB SSD, and it made a noticeable difference. Not a speed demon, but a pleasant improvement, particularly in booting up and shutting down. And the G5 is easy enough to open and install an SSD internally.
I have no desire to open any other iMac to swap in an SSD. So now I have a Late 2015 with a Fusion Drive and USB3 and that's good enough for me.
