Waxcylinder is rather keen on Brian Davies restoration software … https://forum.audacityteam.org/t/click-pop-removal-clickrepair-software/1933/1
I’ve not tried the Brian Davies software but I have tried Goldwave whose noise reduction is better than Audacity IMO.
I believe both Brian Davies and Goldwave have free trials, so you can try before you buy.
