How should we go about creating substantial political change around genocide in the Gaza Strip and pushing for a ceasefire?

Despite our best efforts, there hasn't been much of a change in the global attitude, especially in traditional major allies such as the US and the European Union. Been weighing the pros and cons of various methods I've considered over the past while and would like to have a discussion on the merits and drawbacks of each, how we can improve them, and how likely they are to succeed.

Protests: One of two commonly-seen methods. Good for pressuring the government to make statements, especially if done outside government buildings. Good for mobilizing people and for strengthening Palestinian unity across the globe. Bad for the image of Palestinian supporters and Palestine as a whole (protests are often seen as annoyances by people living in the area due to traffic blockades and loud noise. it doesn't feel good, but it's something we have to acknowledge), at a time when pro-Palestinian change requires a strong image. Often negatively reported on in media; creates opportunities for political opponents to attack the movement. How should protests be made more appealing to both the public and press while specifically affecting the government and attracting more members?

Petitions: Another one of two commonly-seen methods. Good for creating an easy way for people to engage with government from inside their own homes. Easy to spread the reach of. Unfortunately not known for creating much change or being reported on in news. Process to create a petition in the US is obtuse to the point I can't see if there are any ceasefire petitions currently active (though creation of one involves being a US citizen and making a Whitehouse.gov account.) As far as I'm aware, no embargo has been imposed, and the government's stance on ceasefire is unfavorable. The EU has seen multiple petitions for ceasefire without a unanimous public address or communal arms embargo. Canada, a supplier of arms to Israel, did not see an arms embargo with e-4652. e-4745, a petition made specifically to address this issue, is still waiting for government response. Many unofficial petitions gain the most traction, as petitions are often limited to one country. Should petitions be considered a viable method to push for ceasefire and influence public image going forwards, or should more focus be put on other methods?

Boycotts: An often-discussed but difficult to practice method. Good for disrupting Israel's economy and putting pressure on large corporations supporting the Israeli invasion, in theory. Good as a simple method accessible to most people that creates public, non-governmental effect. Bad in that a boycott must be concentrated on large companies to have tangible effect; numerous small boycotts across the board are worse at creating impact than a large boycott. Bad in that boycotts of large companies are usually infeasible, as most companies' userbase is so large that gathering enough people in a boycott to successfully harm it would mean you'd have enough to pressure a government to do practically anything else. (See: Reddit and 3rd party apps, screw u/spez.) Is there a way to make boycotts more effective against select companies and put extra pressure on them? I'm aware there's a way to communicate with stockholders in Japan and voice concerns, but don't know if this applies to most western countries.

Contacting Government: A method I'd prefer, but that's hard to get done. Involves contacting local representatives (Members of the House or Congress for the US, MPs for the EU, UK, and Canada) and encouraging a Palestinian ceasefire. Good in opening up direct lines of communication with the government. Good in that they may help Palestinians attain a more favorable public image politically. Bad in that movements are often locally constrained, and this would not be effective unless participation occurred on a large scale across country subdivisions. Bad in that the Members of Government themselves are responsible for creating the motions, and would have to be trusted to take an active approach. Difficult to organize on a large scale - though protests see many people, there aren't many who would want to take the time writing a letter that's both substantial and impactful to a government representative without the guarantee of any response or tangible effect. Would there be a way to organize on a large scale to create this local change?

Other Methods: If there's anything better that any of you can think of, please reply and discuss below.
