I just want to point out that the use of 既然 or 鉴于 is redudant in many of the examples. "鉴于天气不好，比赛被推迟了" can be shorten to "天气不好，比赛被推迟了" without any loss in meaning, which makes the later form generally better.

Lets look at my hk dictionary (cantonese and english definitions of standard chinese terms and their use)

既然:

用嚟帶出對情況嘅客觀描述, 同埋相關嘅見解、建議或者提問
since; now that; followed by an objective description of the situation, and then an opinion, advice or question related to that situation

VARIANT OF 鑑於〔鉴于〕

標示一啲令事件發生嘅直接或者間接因素, 係正式嘅講法
in the light of; in view of; seeing that

So I would say that the meaning itself is the same, and they are both standard conjunctions. However 既然 has a slightly more specific sentence structure and format to describe a situation and add new info to the context.

### Answer by username_6 on 2023-10-17. Score: 0

Both "鉴于" and "既然" are used in reasoning the conclusion or follow-up action for a matter/event in the foreground.

**鉴于"A", therefore "B"** - "B" is the conclusive result after the consideration/examination/study carefully the matter/event "A".

* 鉴于[A]天气不好，(therefore) [B]比赛被推迟了。

**既然"A", then "B"** - "B" is the logical result of the matter/event "A".

* 既然[A]你喜欢音乐，(then) [B]为什么不考虑学乐器呢？

Note: The root meanings of 鉴 and 既 may help in distinguishing these terms too.

* "鉴" - 镜子 (mirror); 观察 (observe, examine, inspect); 审察 (study carefully, examine). Thus "鉴于" literally means "based on the observation/examination/inspection of", or simply "in view/consideration/the light of", something in the foreground - 考虑到, 由于, 根据.
* "既" - 已经 (already). "既然", literally means "since/as/now that", and typically is associated with a logical conclusion or action deduced/drawn from something happening in the foreground.
