I recently did the same with 8mm films.
A few things I found after many attempts (I used a Wolverine scanner).
Clean the lens and light plate before scanning. Break film reals up into scans of set length (I did about 15 minutes), reclean, backup several frames to cause overlap and startup again.
Try to break up the scans at cut points in the film. This seemed to help with jitter. If I got severe jitter, I would rescan. Expect some misregistration jitter, but not severe jumping.
The scanner created clips of 20fps. I set the clip attribute to 16 fps but the project at 24 fps in resolve. 8mm was generally shot at 15 or 16 fps.
Finally, in resolve I did the following:
Project:
1920x1080 HD
24 fps timeline
Optical Flow
Enhanced Better
Small
On Edit page:
Stabilize:
Transition
Zoom (checked)
Cropping Ratio: .25
Smooth: .25
Crop as needed to clean edges.
On Color page:
Use the Blur section and set to Sharpen. Use as much as can be tolerated (I generally set to 30) in one node.
Add a second note for Noise Reduction. Again as much as can be tolerated. I heavily used both Temporal (Better, Small) and Spacial (Faster, Small).
In another node I did any color and exposure adjustments.
Last I added film grain as an adjustment clip.
Generally this produced good results. Sometimes the optical flow would give strange effects, but overall the quality is very watchable even on large screen formats.
My films are more in the 50 to 60 year old range. I did notice film stock improved over time. I know during this period there was rapid change in the industry, so I can't say if this will work as well for 70 year old film stock.
