LNice thread mine.
These days I use a medium-small size slide hammer with a fitting, that slips in and hooks over the back of the bearing.
Wouldn't re use the bearing though if pulled out in this way.
And for aligning clutch I have the input drive of a t5 I pulled out of one I broke.
I've not seen spigot bearings without sealed race, if it's a serviceable/exposed cage style bearing then yeah I can see where the troubles lie. Good idea jamming paper in against the bearing to seal it and get it to work though.
