Sadly, I have attended five funerals this year. All of them have been via Zoom links. Under normal circumstances I would have not been able to attend two of them due to distance. One of the occasions had friends and relatives from USA and Australia. So it does have its advantages to have these new technologies, and may well be the way forward in the future.
My thought on the original question - it certainly depends on the person making the arrangements. They will know who the deceased was closest to, and who would want to attend in person. No-one should feel they have a "right" to attend. That could mean that all the relatives are left out, and close friends included.
