When you say "people must still be coming over", the people in question are EU citizens with a permanent right of free entry to Spain and also the right to live there. As for the TV programmes showing property in Spain, if you take a look at the production year of the programme in the closing credits (usually in Roman numerals), you will find they are from a year when it was OK for Brits to buy property in Spain. In other words the programmes were produced before the end of the transition period which ended on 31 January 2021.
Brits already living in Spain had no worries because they were covered by the terms of the Brexit Withdrawal Agreement.
I don't wish to rain on your parade but unless you have a lot of money, it could be prohibitively expensive for you to move to Spain or any other EU country. Your only other option is to move to the Republic of Ireland where you would be covered by the terms of the 1922 Common Travel Area agreement.
