Personally I'd purchase the biggest internal storage capacity I could afford @sarasphotobox
Daily Driver > Samsung Galaxy s²² Ultra 256Gb in Phantom Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
Hi @sarasphotobox Nowadays many people use cloud storage which is the main reason the SD card slot was removed. However there are alternatives such as an USB-C connector,Flash Drive or Portable SSD. See some information here https://www.androidcentral.com/best-microsd-alternatives-samsung-galaxy-s21
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB

@sarasphotobox: I recommend utilising cloud storage (Samsung Cloud, OneDrive and Google Drive) for your personal data and media files via Settings > Accounts and Backup, and leaving your internal storage free for your games and apps.
