There are some threads where we discussed similar either here or on dpreview. When I find them tomorrow/today ( too hot to sleep ) I will post a link.
Am about 3/4 through scanning our col negs and some slides. A load of aps went to MrScan who dumped tiffs to a dropbox acc -they did a great job.
Am using a Reflecta Proscan 10T from scandig.de. It came with a version of silverfast which I struggled with so I switched to vuescan which works for me. Since you are using silverfast prob. no point in going through my settings. so just general stuff:
All I am trying to do is to regain images for display on a screen/tv and maybe print a few 5x7 and a very few up to a4. These are all from consumer films: konica/ agfa/ kodak and some fp4/hps - nothing special - nor are the pictures just snapograms.
I scan just to 4k - tried higher resolutions but never seen any inprovement
I do use the IR scratch detection filter but at its lowest setting. No other sharpening or grain reduction apart from vuescans jpeg engine.
Now, I profile the film base on every roll first - successful only about 70% of time.
Scan to jpegs - mostly but for important stuff to raw/tiff though I have never managed to get any more information from the tiffs than I can get from jpeg .
Have used LR for post in the past but now use dxo pl4- personal choice but easy for me to adjust global parameters, some NR if nec. but mainly exposure, WB, channel saturation tones using HSL colour wheel etc etc. So again my experience - not much use to you. In general, I do as little as possible in Vuescan, mostly leaving it in "generic" settings and leave tweaking to post - I have tried other strategies but none work as well for me. Silverfast may be totally different of course.
I think the "proper" way is to take raw neg into Post and use
Colorperfect. I don’t bother.
Now happy with the results I am getting - even managed to recover decent images from old ? faded slides from a half frame penF from the 70’s. Most negs taken just by my wife on her minolta x700 and my self on contax with zeiss glass. Recent negs of mine on lots of cameras/lenses.
Happy scanning!

ps last year I thought I would have another go with silverfast but i had changed my mac and the license key wouldn’t work. Neither silverfast nor scandig responded to emails - I should just have phoned them but I gave up.
EDIT the link was:
a Vuescan users thread so probably not too much use to you. Chris R ( above ) started a thread on scanning which I found really useful. He hasn't mentioned it so I will
