I finally was able to successfully get the XFCE Netinstall version installed.
However, once installed I had weird wifi connectivity problems w. 2 wifi access

I don't know about the rest of it, but modern versions of OpenSSH have
disabled some crypto algorithms by default. A common one is the ssh-rsa
host key algorithm. The failure message gives you a clue (but sometimes
ONLY a clue) as to what option you need to activate them again. You can
re-enable them from the command line, using for example:
ssh -ohostkeyalgorithms=+ssh-rsa username@hostname
Or, you can get fancy with .ssh/config and associate a host entry with
the needed options, e.g.
Host hostname
User username
HostKeyAlgorithms +ssh-rsa
or something vague like that (I didn't check the syntax of the option),
maybe someone can correct me.
Of course, they weren't deprecated without a reason. When you encounter
these messages, you should consider whether you can update the remote
system to not rely on the deprecated algorithms, because the pain is
only likely to increase in the future.
On older Debian, you are probably running a not-yet-fully-modern openssh
and therefore have not encountered the deprecations yet.
As for the slowness, at the risk of repeating the obvious, because
reaching services over the internet crosses potentially many hops and
depends on many things working, it's hard to say anything definitive
without testing. Could be long DNS delays, could be an overloaded link
somewhere along the path, it could be the server at the far end was
overloaded. The "mtr" tool is a good place to start, as packet loss or
big jumps in delay along the path can give clues. I haven't installed
Debian in a while, so I don't have any particular insight or recent
experience to share.
