I don't agree with some users recommending Acros 100 and Delta or TMax 100, these are high contrast films.
I recommend Adox 20, 50 or 100 or Fomapan films in Rodinal - stand developed 1/100 and for 60 mins. Also, HP5 400 in stand development will give you very interesting smooth grayscales. It's the grayscales, the resolution of the films and the sharp lenses that will give you that creamy look. Avoid high contrast films and normal agitation unless somehow you can pull the creamy "50's" large format look in 35mm. Preferably, go for the slow, hi res films. With Ilford Pan F 50, you need to tame the highlights - so this means stand development.
Some examples:
Leica Summicron 50/2 DR, Green Filter, f4
Fomapan 100, Adonal 1/100 Stand Development @ 60 mins, normal rfix and rinse
