Let's see for the Netherlands.
NOS (public broadcaster)
Standard stuff like highlights of the Dutch football competition, live speed skating when it's world/European championships or a World Cup in Heerenveen sometimes, plus national championships usually. Quite a lot of cycling live, like the main classics and the Tour de France (not the Giro d'Italia, that's exclusively for Eurosport, or Vuelta, because they don't care). World and European championships of sports like field hockey, volleyball or water polo are usually shown (at least the Dutch matches), just like all matches in the World Cup and European championships in football. They're also showing more and more on their website when it's not on TV, like all speed skating World Cups.
RTL7 (commercial)
Generally speaking it's a regular commercial TV channel, as for sports their main things are darts (PDC, not BDO), which they show a lot, and Europa League football. Also in weekends they have some programs about local car racing sometimes. Every now and then they show live boxing, usually when it's between 20.00 and midnight, stuff like the Joshua fights, but not the fights in the USA.
Veronica (commercial)
Another regular commercial TV channel, as for sports they show Champions League football and since a while they have the rights for Glory kickboxing, which sucks since they only show the events live when it's at a 'good' time (and only the main fights, the rest they quickly show in around 20 seconds per fight), whereas the previous right-holders showed everything live no matter the time of day. I believe they got UFC rights as well, which is fine for me since I watch that much later and online.
Ziggo Sport (paid sports channel)
Shows quite a lot on their 7-8 channels. They have dedicated tennis, golf and racing channels, with most PGA and European Tour events and a boatload of motorsports (F1, NASCAR, IndyCar, DTM, Euro F3, GP2, GP3, WRX and sometimes even German F4, all live), plus they've got rights for Champions League football, all the women's (national team) handball, a few NBA matches per week, ski- and snowboard cross, cyclocross Superprestige and I'm sure I'm forgetting a lot. Also football, but I'm not sure which competition is here and which is at their rival (like Bundesliga, Serie A, Premier League etc). They've also got a few cycling races, like the recent Tour Down Under.
Fox Sports (paid sports channel divided into Dutch competition football and an international subscription)
A LOT of live football, from the Dutch competition to Europa League and the main European competitions, but also South American football, African CL, a ton of national team football. Weekly live NFL games (all Thursday + Monday night games, three Sunday night games and all postseason games), all UFC live (although I'm not sure they still have it now that Veronica bought the rights), a few live NHL games, live MLB and basically all postseason live. Some live amateur football on weekends and probably some more stuff.
Eurosport
The main channel for sports, promoting itself as 'The home of cycling' and 'The home of the Olympics', since they've got exclusive rights for a lot of it. This is where most winter sports are shown (especially if you combine it with the Eurosport Player you can watch basically anything, live and on-demand, except the IBSF sports), HUGE amounts of cycling are shown there, still too much football as well. They also have all exclusive rights for MotoGP/2/3 (all trainings, qualifyings and races) plus WTCR and things like Le Mans. Sometimes you can catch some minor sports on here, so if that's all you're looking for, Eurosport is your best guess. Still, since they got more and more big rights, they are showing less and less of the minor sports (except for winter sports, that stays).
