i lived in silicon oasis with my family for 1.5 years and it was heaven! we had 2 mosques, a shopping center (silicon central that includes Lulu and a lot of clothing shops and cafes/restaurants), the north park, a lake, a food court, and 2 hospitals nearby, with multiple grocery shops like al maya and choithrams, and many bus stops that go almost everywhere around silicon and dubai. i gave it 4/5 on the transport only because we don't have metro line however you can take bus number 320 to al rashidya (centerpoint metro) which takes about 30-40 mins or bus #50 which goes to dubai mall directly in about 30-40 mins too
when it comes to being family friendly, i have a 2 year old who loved to go to the north park as there's a lot of slides and swings for kids as well as a large football court and a running track around the court. there's also basketball and beach ball/volley ball courts and a skating area. when it comes to running/walking there's a running track around the lake. i used to take my scooter from the park all the way to silicon central mall.
we also had a small shopping/cafe area known as Souq Extra that included carrefour, kfc, krispy kreme...etc, as well as 2 gyms including Gymnation and UFC in silicon central mall
noon supermall, and minutes were right around the corner (we had a noon minutes warehouse inside souq extra) so deliveries were really quick
i would say the only negative/downsides is that it gets a bit traffic crowded around 5-7pm and rent may be a bit overpriced especially near the mall and around bus stations, but it gives you that value for money vibe, honestly i really wish i could go back and live there again
