There have not been Sadduccee since the temple was destroyed. They did not believe in the afterlife or any kind of resurrection, because it was not in the Torah. I will also say that the concept of angel is different between Judaism and Christianity.. Angels are mentioned in Genesis, so that concept would not be off the table for them.
When it comes to the idea of the afterlife and the resurrection, those concepts are not as firmly entrenched in dogma as it is in the Christian religion. There is much more variation in belief about it, but the importance of the belief is not stressed at all. You can have two people who go to the same temple, are equally religious, and one could belief in the afterlife, the other does not. .. and it won't matter at all. The emphasis of Judaism is not on the afterlife, but rather on living this life. There are even Jewish groups (many of the Chasidic Jews for example) that believe in reincarnation. While many are concerned about the afterlife, not an insignificant number are not. A common response would be 'I'll leave it in the hands of the Creator'
One of the issues is that we are to serve god not for reward, but for it's own sake. Some people say to worry about the afterlife and based your actions on the afterlife is doing good deeds for a reward in the afterlife. So, to worry about the afterlife and the resurrection is to take away from serving God for it's own sake.. (for some).
Because the dogma about the afterlife is so vaguely defined, there are many many variations of belief on it, but no one specific notion is promoted over another notion.
