<li>I find <a href="https://brickset.com/parts" rel="nofollow noreferrer" title="BrickSet">BrickSet</a> a bit easier to browse for parts than BrickLink</li>

You'll need to start learning the nomenclature for those pieces.

For example the long straight pieces you have there with holes on top are "[Technic, Brick 1 x 12 with Holes](https://www.bricklink.com/v2/catalog/catalogitem.page?P=3895#T=C)"

The pieces with rounded ends are lift arms. You can browse through [the list](https://www.bricklink.com/catalogList.asp?catType=P&catString=137) of them here or take a stab at their descriptions using the width and number of pin holes. For example the purple on you have there is

* 1 hole wide
* 9 holes long
* as think as a normal LEGO brick (some are half that thickness)
* Bent with 6 on one line and 4 on the other

  so "[Technic, Liftarm 1 x 9 Bent (6 - 4) Thick](https://www.bricklink.com/v2/catalog/catalogitem.page?P=6629#T=C)"
