My big fear is being forced to accept digital (ink jet) prints from my negatives. I have NO experience in what those will look like compared to analogue and fear that I will not be happy with that. Your take?
The general consensus in the forum, supported by the opinion of competent people like PE, is that for various reasons colour negatives are much less at risk than slide film. Black & White is totally out of extinction risk, colour negative is closely observed, slide film is on the Appendix I of CITES

Regarding printing, you will always be able to print colour negatives to chemical papers using laboratories which use machines like the Durst Lambda. Those machines scan the negative, obtain a digital image which they use to project coloured light on the photographic paper (just like an enlarger would do) which is then developed chemically. It's a hybrid process which belong to this forum as most participants just ignore that when they bring their negative film to be developed and printed the most likely occurrence is that the printing is hybrid.
Actually I suspect a Durst Lambda is able to print a positive with just the same ease as it prints a negative. Those machines are not produced any more but should certainly remain working for many years. Besides, production can resume one day. It's like with film cameras: new ones are scarcely produced now because the second-hand market satisfies the demand.
I think you can buy that GF670 with high confidence that you will be able to use it with black & white and with colour negatives and have them printed on chemical papers for many years to come.
