orientation
The ability to determine one’s own position in space and find the right way.
In dem dichten Wald verlor ich schnell die Orientierung.

The word ends in '-ung', which is typical for feminine nouns derived from a verb. The base is the verb 'sich orientieren' (to orient oneself / find one’s way), which means 'sich zurechtfinden' (to find one’s way).
Er musste sich in der neuen Stadt erst orientieren.
He first had to orient himself in the new city.
The word comes from 'der Orient' (the East). In the past, people oriented themselves by the position of the sun in the east in order to find direction. This basic idea of 'finding direction' is present in all meanings.
Die Sonne geht im Orient auf.
The sun rises in the Orient.
In the spatial sense, 'Orientierung' (orientation) is often combined with the verbs 'verlieren' (to lose), 'haben' (to have), or 'behalten' (to keep). A person with a good 'Orientierungssinn' (sense of direction) can find their way easily.

When it is about content-based guidance, 'Orientierung' (guidance) is often used with verbs such as 'geben' (to give), 'bieten' (to offer/provide), or 'dienen' (to serve). Something helps someone understand a topic.

When it is about personal goals, 'Orientierung' (orientation) is often used with 'suchen' (to look for) or 'finden' (to find). People then speak, for example, of 'berufliche Orientierung' (career orientation) or 'politische Orientierung' (political orientation).

direction
'die Richtung' and 'die Orientierung' can both help you understand where to go or how to act. 'die Richtung' more often names the path, the line, or the goal. 'die Orientierung' more often means the ability or help needed to find your way, either in physical space or in a difficult topic. You can also speak of 'Orientierung' when talking about goals and values. Learners confuse the words because both have to do with 'sich zurechtfinden' (finding your way / getting your bearings). If you mean the path itself, use 'Richtung' more often. If you mean help, an overview, or inner guiding principles, 'Orientierung' fits better.
