According to the kokugos, it's always for a person's future.
I think a simple note like this is sufficient.

Google news, search for "嘱望".  There are other uses, but more than half seem to be 将来を嘱望. Almost all され

yourei for 嘱望, mostly 将来を〜される

Could make a dedicated entry？:
nikk? 将来を嘱望される
読み方：しょうらいをしょくぼうされる
別表記：将来を嘱望されている、未来を嘱望される、未来を嘱望されている
将来にかけて大きく成長するであろうと期待がかけられるさま。
https://www.weblio.jp/content/将来を嘱望される#:~:text=将来にかけて大きく成長する,期待がかけられるさま。

https://ejje.weblio.jp/content/将来性のある人物
将来を嘱望される若者
例文a promising youth

many reverso examples, often glossed as "promising". saw a "they have great aspirations for the future", "outstanding potential"

In spite of 期待 being vastly more common, in this structure 嘱望 wins.　I think this is remarkable.
期待	30306682	99.8%
嘱望	31883	0.1%

将来を嘱望さ	21771
将来を期待さ	9862

Open to better/alternative suggestions.

I was trying to figure out the grammatical structure of this thing, and discovered that it is overwhelmingly used in one particular structure (or minor variations thereof).
"to have a promising future", "to have high hopes of another's future prospects", etc.

Even when not in this structure, される is almost always used. (can follow が、と、を、で,etc.）

Note particularly my referenced comparison with 期待 in the same structure.
